C# CodeDom：自定义 class 作为字符串代码中的参数

Question

抱歉，我是使用 CodeDom 编程的新手，我遇到了无法解决的问题。正在考虑你们中的一些人是否知道解决方案。

我在 class 文件中有以下代码：

public class AnotherCustomClass {
    public string Employer { get; set; }
    public DateTime? DateOfHire { get; set; }
}

public class CustomClass {
    public int X { get; set; }
    public int Y { get; set; }
    public AnotherCustomClass[] YetAnother { get; set; }
}

public void DoSomething()
{
    string expression = @"using System;  
    namespace MyNamespace {
        public class MyClass {
            public static int DoStuff(CustomClass myCustomClass) {
                return myCustomClass.X + myCustomClass.Y;
            }
        }
    }";

    CSharpCodeProvider provider = new CSharpCodeProvider();
    CompilerParameters assemblies = new CompilerParameters(new[] { "System.Core.dll" });
    CompilerResults results = provider.CompileAssemblyFromSource(assemblies, expression);
    Type temporaryClass = results.CompiledAssembly.GetType("MyNamespace.MyClass");
    MethodInfo temporaryFunction = temporaryClass.GetMethod("DoStuff");
    CustomClass data = new CustomClass() { X = 1, Y = 2 };
    object result = temporaryFunction.Invoke(null, new object[] { data });
    return result;
}

我想输入 data（自定义创建的 class，其中包含另一个自定义 class 的数组）变量作为参数在 DoStuff 函数中，我一直有错误。有办法解决这个问题吗？

多处错误，改成这样：

string expression = @"using System;  
namespace MyNamespace {
    public class MyClass {
        public static int DoStuff(CustomClass myCustomClass) {
            return myCustomClass.X + myCustomClass.Y;
        }
    }

    public class CustomClass
    {
        public int X;
        public int Y;
        public CustomClass(int x, int y) { X = x; Y = y; }
    }
}";

CSharpCodeProvider provider = new CSharpCodeProvider();
CompilerParameters assemblies = new CompilerParameters(new string[] { "System.dll" });
CompilerResults results = provider.CompileAssemblyFromSource(assemblies, expression);
Type temporaryClass = results.CompiledAssembly.GetType("MyNamespace.MyClass");
Type parClass = results.CompiledAssembly.GetType("MyNamespace.CustomClass");
MethodInfo temporaryFunction = temporaryClass.GetMethod("DoStuff");
object mc = parClass.GetConstructor(new Type[] { typeof(int), typeof(int) }).Invoke(new object[]{1,2});
object result = temporaryFunction.Invoke(null, new object[] { mc });
