相关疑难解决方法(0)

我有一个win表单应用程序,其中列表框显示方法(按属性).我试图动态调用线程中的方法,使用反射从列表框的选定值获取方法信息.但是,当调用Methodinfo.Invoke时,我得到了这个内部异常"非静态方法需要一个目标C#".

这是我的代码(请记住,我仍然是c#和编程的新手.)

        items.Add(new KeyValuePair<String, MethodInfo>(
            token.DisplayName, method));

    }

    testListBox.DataSource = items;
    testListBox.DisplayMember = "Key";
    testListBox.ValueMember = "Value";
}

public void GetTest()
{//The next two methods handle selected value of the listbox and invoke …
