如何使用CodeDomProvider获取输出？

I can use CodeDomProvider for compiling the C# Code. I compiled and got the compiled result. But I want to get the output of the code snippet below. How do i get this?

我可以使用CodeDomProvider来编译C#代码。我编译并得到了编译结果。但我想得到下面代码片段的输出。我怎么得到这个?

e.g.:

for(int i=0;i<=5;i++)
{
    System.Console.WriteLine(i);
}

The above code is what i am using. I can successfully compile it but did not get the result. How can I get the result?

上面的代码是我正在使用的。我可以成功编译它但没有得到结果。我怎样才能得到结果?

Yes you can compile and get the results too. You need to have your code under namespace and within a function

是的,你可以编译并获得结果。您需要在命名空间和函数内使用代码

CompilerResults results = provider.CompileAssemblyFromSource(parameters, code);

Assembly assembly = results.CompiledAssembly;
Type program = assembly.GetType("Dynamic.Test");
MethodInfo main = program.GetMethod("Test");
main.Invoke(null, null);

Created below program with some modifications to read result. Hope this helps.

在程序下创建,对读取结果进行一些修改。希望这可以帮助。
