NUnit:如何在C#中使用"ref"参数测试私有方法

public class MyClass
{
    private void MyPrivateMethod(ref int value)
    {
        value += 10;
    }
}

using NUnit.Framework;
using System.Reflection;

[TestFixture]
public class MyClassTests
{
    [Test]
    public void MyPrivateMethod_RefParameter_IncrementsValueByTen()
    {
        // Arrange
        MyClass myClass = new MyClass();
        int value = 5;
        MethodInfo methodInfo = typeof(MyClass).GetMethod("MyPrivateMethod", BindingFlags.NonPublic | BindingFlags.Instance);

        // Act
        object[] parameters = new object[] { value };
        methodInfo.Invoke(myClass, parameters);
        value = (int)parameters[0];

        // Assert
        Assert.AreEqual(15, value);
    }
}
