CodeDomProvider.CreateCompiler（）已过时

Question

CSharpCodeProvider codeProvider = new CSharpCodeProvider();
ICodeCompiler MyCompiler = codeProvider.CreateCompiler();
CompilerParameters myParameters = new CompilerParameters();
myParameters.GenerateExecutable = true;
myParameters.OutputAssembly = @"prog.exe";
myParameters.TreatWarningsAsErrors = false;
CompilerResults results = myCompiler.CompileAssemblyFromFile(myParameters,"prog.txt");

如何编写此代码以消除此警告：

  

System.CodeDom.Compiler.CodeDomProvider.CreateCompiler（）'已过时：'“调用者不应使用ICodeCompiler接口，而应直接在CodeDomProvider类上使用这些方法。从CodeDomProvider继承的方法仍然必须实现此接口，并且应排除此警告或废弃此方法。**

Answer 1

改为使用this method：

CodeDomProvider provider = CodeDomProvider.CreateProvider("CSharp");

扩展：

if (CodeDomProvider.IsDefinedLanguage(language))
{
    CodeDomProvider provider = CodeDomProvider.CreateProvider(language);
    // ...
}
else
    Console.WriteLine("ERROR");

Answer 2

CSharpCodeProvider codeProvider = new CSharpCodeProvider();
CompilerParameters myParameters = new CompilerParameters();
myParameters.GenerateExecutable = true;
myParameters.OutputAssembly = @"prog.exe";
myParameters.TreatWarningsAsErrors = false;
CompilerResults results = codeProvider.CompileAssemblyFromFile(myParameters, "prog.txt");
