如何使这个类通用？(.NET C#)

public interface IMyInterface
{
    void MyMethod();
    string MyProperty { get; set; }
}

public class MyClass : IMyInterface
{
    public void MyMethod()
    {
        // 实现方法
    }

    public string MyProperty { get; set; }
}

public class MyGenericClass<T> where T : IMyInterface
{
    private T _myObject;

    public MyGenericClass(T myObject)
    {
        _myObject = myObject;
    }

    public void DoSomething()
    {
        _myObject.MyMethod();
    }
}

public class MyDependencyInjectionClass
{
    private readonly IMyInterface _myInterface;

    public MyDependencyInjectionClass(IMyInterface myInterface)
    {
        _myInterface = myInterface;
    }

    public void DoSomething()
    {
        _myInterface.MyMethod();
    }
}
