用C#在VB中通过MOQ设置引用参数

Imports System.Runtime.InteropServices

using Moq;

namespace YourNamespace
{
    public static class MockHelper
    {
        public static void SetupRefParameter<T>(Mock<T> mock, ref T value)
        {
            mock.Setup(m => m.MethodWithRefParameter(ref value)).Callback(new Action<T>(newValue => value = newValue));
        }
    }
}

Imports YourNamespace

Module Program
    Sub Main()
        Dim mock As New Mock(Of IYourInterface)()
        Dim value As String = "initial value"

        MockHelper.SetupRefParameter(mock, value)

        ' 调用方法，传入引用参数
        Dim result As String = mock.Object.MethodWithRefParameter(value)

        Console.WriteLine(result) ' 输出设置后的引用参数值
    End Sub
End Module
