从.cs文件获取特定方法源代码(在运行时)

Question

1 -我在光盘上有这个文件内容(cs文件,未编译):

    namespace Test
    {
        using System;
        public class TestClass 
        {
            public string SomeTestMethod(){
                return "test here";
            }
        }
    }

如何将运行时间输入变量方法:

public string SomeTestMethod(){
    return "test here";
}

例如: SourceCodeParser.GetMothod("path to file","SomeTestMethod");

2 - 访问者成员的内容是否可能？

   public string SomeMember {
        get {
            return "test here";
        }
    }

罗斯林是你需要的.您可以使用nuget轻松安装它.这是获取方法体的工作代码:

string GetMethod(string filename, string methodName)
{
    var syntaxTree = SyntaxTree.ParseFile(filename);
    var root = syntaxTree.GetRoot();
    var method = root.DescendantNodes()
                     .OfType<MethodDeclarationSyntax>()
                     .Where(md => md.Identifier.ValueText.Equals(methodName))
                     .FirstOrDefault();
    return method.ToString();
}

以及获取属性getter的代码:

string GetPropertyGetter(string filename, string propertyName)
{
    var syntaxTree = SyntaxTree.ParseFile(filename);
    var root = syntaxTree.GetRoot();
    var property = root.DescendantNodes()
                       .OfType<PropertyDeclarationSyntax>()
                       .Where(md => md.Identifier.ValueText.Equals(propertyName))
                       .FirstOrDefault();
    var getter = property.AccessorList.Accessors.First(a => a.Kind == SyntaxKind.GetAccessorDeclaration);
    return getter.ToString();
}
