我如何解决C#在Generic类型上调用静态函数的限制

public static class GenericHelper
{
    public static void DoSomething<T>()
    {
        T.StaticMethod();
    }
}

public static class GenericHelper
{
    public static void DoSomething<T>()
    {
        var method = typeof(T).GetMethod("StaticMethod");
        method.Invoke(null, null);
    }
}

public interface IStaticMethod
{
    void StaticMethod();
}

public static class GenericHelper
{
    public static void DoSomething<T>() where T : IStaticMethod
    {
        T.StaticMethod();
    }
}
