C#将部分Controls数据导入对象并存入ini中的操作方法_C#

在日常的winform设计工作中，将控件中的数据导出到对应属性或者字段中，再进行保存是经常会用到的技巧；最简单的就是同时遍历控件和遍历属性字段进行名称对比（需要保证控件的名称要包含在字段属性中）；

本篇文章主要是在简单的基础上优化整体逻辑，不仅仅是只遍历控件和属性进行名称对比（适合类），还包含一些筛选；

1.遍历控件和属性得到控件的值

在下面代码中，控件命名是以textbox_one的形式命名的

///类对象
class objectparm
    {
        public int one;
        public string two;
        public int three;
        public string four;
        public int five;
        public string six;
    }

private void save(objectparm objectparm, control controls, string textname = "textbox_", string comboboxname = "combobox_")
        {
            type type = objectparm.gettype();
            //获取有关成员属性的信息以及提供对成员数据的访问
            memberinfo[] memberinfos = type.getmembers();//获取所有公共成员
            foreach (control control in controls.controls)
            {
                foreach (memberinfo item in memberinfos)
                {
                    //这里字段属性均可以
                    if (item.membertype == membertypes.field)
                    {
                        if (control is combobox)
                        {
                            if (control.name == comboboxname + item.name)
                            {
                                string value = control.text;
                                //需要筛选对象属性的类型
                                setmembervalue(objectparm, item.name, value);
//---------------------------------注意----------------------------------
//setmembervalue函数是判断属性或者字段的类型，根据类型进行不同的赋值
                            }
                        }
                        else if (control is textbox)
                        {
                            if (control.name == textname + item.name)
                            {
                                string value = control.text;
                                //需要筛选对象属性的类型
                                setmembervalue(objectparm,item.name,value);
                            }
                        }
                    }
                }
            }
        }

2.利用fieldinfo的getset函数设置类对象数据

/// <summary>
        /// 设置类对象成员数据
        /// </summary>
        /// <param name="objectparm"></param>
        /// <param name="filename"></param>
        /// <param name="filevalue"></param>
//istype函数是对比类型是否一致
        private bool setmembervalue(objectparm objectparm, string filename, string filevalue)
        {
            type type = objectparm.gettype();
            //发现字段属性并提供访问
            fieldinfo fieldinfo = type.getfield(filename);//搜索字段
            bool converflag = true;
            //类型匹配
            if (istype(fieldinfo.fieldtype, "system.string"))
            {
                fieldinfo.setvalue(objectparm, filevalue);
            }
            if (istype(fieldinfo.fieldtype, "system.double"))
            {
                //判断是否可以进行转
                double result = 0;
                if (!double.tryparse(filevalue, out result)) converflag = false;
                fieldinfo.setvalue(objectparm, result);
            }
            if (istype(fieldinfo.fieldtype, "system.single"))
            {
                float result = 0;
                if (!float.tryparse(filename, out result))
                    converflag = false;
                fieldinfo.setvalue(objectparm, result);
            }
            if (istype(fieldinfo.fieldtype, "system.boolean"))
            {
                bool flag = false;
                if (!boolean.tryparse(filename, out flag))
                    converflag = false;
                fieldinfo.setvalue(objectparm, flag);
            }
            if (istype(fieldinfo.fieldtype, "system.uint32"))
            {
                uint value = 0;
                if (!uint.tryparse(filename, out value))
                    converflag = false;
                fieldinfo.setvalue(objectparm, value);
            }
            if (istype(fieldinfo.fieldtype, "system.uint16"))
            {
                uint16 value = 0;
                if (!uint16.tryparse(filename, out value))
                    converflag = false;
                fieldinfo.setvalue(objectparm, value);
            }
            if (istype(fieldinfo.fieldtype, "system.int32"))
            {
                int value = 0;
                if (!int32.tryparse(filename, out value))
                    converflag = false;
                fieldinfo.setvalue(objectparm, value);
            }
            if (istype(fieldinfo.fieldtype, "system.decimal"))
            {
                if (filevalue != "")
                    fieldinfo.setvalue(objectparm, decimal.parse(filevalue));
                else
                    fieldinfo.setvalue(objectparm, new decimal(0));
            }
            if (istype(fieldinfo.fieldtype, "system.nullable`1[system.datetime]"))
            {
                if (filevalue != "")
                {
                    try
                    {
                        fieldinfo.setvalue(objectparm, (datetime?)datetime.parseexact(filevalue, "yyyy-mm-dd hh:mm:ss", null));
                    }
                    catch
                    {
                        fieldinfo.setvalue(objectparm, (datetime?)datetime.parseexact(filevalue, "yyyy-mm-dd", null));
                    }
                }
                else
                    fieldinfo.setvalue(objectparm, null);
            }
            return converflag;
        }

private bool istype(type type, string typename)
        {
            if (type.tostring() == typename)
            { return true; }
            if (type.tostring() == "system.object")
                return false;
            return istype(type.basetype, typename);
        }

3.ini简易类库编写

class iniclass
    {
        public static string inipath = directory.getcurrentdirectory() + "\\" + "systemset.ini";//这个地方实际没用到，在另外一个地方
        [system.runtime.interopservices.dllimport("kernel32")]
        public static extern long writeprivateprofilestring(string section, string key, string val, string filepath);
        [system.runtime.interopservices.dllimport("kernel32")]
        public static extern int getprivateprofilestring(string section, string key, string def, stringbuilder retval, int size, string filepath);
        public iniclass(string inipath_)
        {
            inipath = inipath_;
        }
        /// ﹤summary﹥   /// 写入ini文件   /// ﹤/summary﹥   /
        // ﹤param name="section"﹥项目名称(如 [typename] )﹤/param﹥   
        /// ﹤param name="key"﹥键﹤/param﹥   
        /// ﹤param name="value"﹥值﹤/param﹥   
        public void iniwritevalue(string section, string key, string value)
        {
            writeprivateprofilestring(section, key, value, inipath);
        }
        /// ﹤summary﹥   
        /// 读出ini文件   
        /// ﹤/summary﹥   
        /// ﹤param name="section"﹥项目名称(如 [typename] )﹤/param﹥   
        /// ﹤param name="key"﹥键﹤/param﹥   
        public string inireadvalue(string section, string key, string default_value = "")
        {
            stringbuilder temp = new stringbuilder(50000);
            int i = getprivateprofilestring(section, key, default_value, temp, 50000, inipath);
            return temp.tostring();
        }

4.存入对象转换为json存入ini

string path = @"e:\ymx\test\将部分controls数据导入对象\sys.ini";
        private void button1_click(object sender, eventargs e)
        {
            save(objectparm,panel1, "textbox_", "combobox_");
            string str = jsonconvert.serializeobject(objectparm);
            //存入ini
            iniclass iniclass = new iniclass(path);
            iniclass.iniwritevalue("parm", "trest", str);
         }
