C#将类型作为变量传递。如何实现？

public class MyClass<T>
{
    private T myVariable;
    
    public void SetVariable(T variable)
    {
        myVariable = variable;
    }
    
    public T GetVariable()
    {
        return myVariable;
    }
}

// 使用示例
MyClass<int> myIntClass = new MyClass<int>();
myIntClass.SetVariable(10);
int intValue = myIntClass.GetVariable();

MyClass<string> myStringClass = new MyClass<string>();
myStringClass.SetVariable("Hello");
string stringValue = myStringClass.GetVariable();

public class MyClass
{
    private object myVariable;
    
    public void SetVariable(Type type, object variable)
    {
        if (variable.GetType() == type)
        {
            myVariable = variable;
        }
        else
        {
            throw new ArgumentException("Invalid type");
        }
    }
    
    public object GetVariable()
    {
        return myVariable;
    }
}

// 使用示例
MyClass myClass = new MyClass();
myClass.SetVariable(typeof(int), 10);
int intValue = (int)myClass.GetVariable();

myClass.SetVariable(typeof(string), "Hello");
string stringValue = (string)myClass.GetVariable();
