我要评论1、目的
分别用代码、模板生成目标代码文件。
方法主要包括文件读写、代码生成函数、及应用程序。
2、文件读写函数
/// <summary>
/// 文本文件写
/// </summary>
/// <param name="path"></param>
/// <param name="str"></param>
public static void writetxt(string path, string str)
{
using (streamwriter writer = new streamwriter(path, true))
{
writer.writeline(str);
writer.close();
}
}
/// <summary>
/// 文本文件读
/// </summary>
/// <param name="path"></param>
/// <returns></returns>
public static string readtxt(string path)
{
try
{
if (!file.exists(path))
{
return null;
}
string str = string.empty;
using (filestream fs = new filestream(path, filemode.open, fileaccess.read))
{
using (streamreader sr = new streamreader(fs))
{
str=sr.readtoend();
sr.close();
}
fs.close();
}
return str;
}
catch (exception e)
{
console.writeline(e.message);
return null;
}
}
3、代码生成函数
/// <summary>
/// 代码生成器（整体生成）
/// </summary>
/// <param name="space"></param>
/// <param name="name"></param>
public static void csharpgenerate(string space,string name)
{
stringbuilder sb = new stringbuilder();
sb.append("using system;\n" +
$"namespace {space}\n" +
"{\n" +
$" public class {name}" +
" {\n" +
" private string name;\n" +
" public void function(string str)\n" +
" {\n" +
" console.writeline(str);\n" +
" }\n" +
" }\n"+
"}\n");
writetxt("e:\\generate.cs", sb.tostring());
}
/// <summary>
/// 代码生成器（分行生成）
/// </summary>
/// <param name="space"></param>
/// <param name="name"></param>
public static void csharpgeneratesplit(string space, string name)
{
stringbuilder sb = new stringbuilder();
sb.append("using system;\n");
sb.append($"namespace {space}\n");
sb.append("{\n");
sb.append($" public class {name}");
sb.append(" {\n");
sb.append(" private string name;\n");
sb.append(" public void function(string str)\n");
sb.append(" {\n");
sb.append(" console.writeline(str);\n");
sb.append(" }\n");
sb.append(" }\n");
sb.append("}\n");
writetxt("e:\\generatesplit.cs", sb.tostring());
}
/// <summary>
/// 代码生成器（模板生成）
/// </summary>
/// <param name="space"></param>
/// <param name="name"></param>
public static void csharpgeneratetemplate(string space, string name)
{
string str = readtxt("e:\\generate.cs");
str = str.replace("demo", space);
str = str.replace("test", name);
writetxt("e:\\generatetemplate.cs", str);
}
4、应用
static void main(string[] args)
{
//csharpgenerate("demo", "test");
//csharpgeneratesplit("demo", "test");
csharpgeneratetemplate("nature", "develop");
}
5、效果
generate.cs文件
using system;
namespace demo
{
public class test {
private string name;
public void function(string str)
{
console.writeline(str);
}
}
}
generatesplit.cs文件
using system;
namespace demo
{
public class test {
private string name;
public void function(string str)
{
console.writeline(str);
}
}
}
generatetemplate.cs文件
using system;
namespace nature
{
public class develop {
private string name;
public void function(string str)
{
console.writeline(str);
}
}
}
