问题 You should be able to create a generic form: public partial class MyGenericForm<T> : Form where T : class { /* form code */ public List<T> TypedList { get; set; } } Is valid C#, and compiles. However the designer won't work and the form will throw a runtime exception if you have any images stating that it cannot find the resource. I think this is because the windows forms designer assumes that the resources will be stored under the simple type's name. 回答1: Yes you can! Here's a blog post I

问题 I am very new to C#, and have a question. I have been able to change the border colors of buttons and such by changing their FlatStyle to "Flat". With the NumericUpDown , I can't change the FlatStyle. I would like to still be able to use the up and down arrows, so just using something else to cover the edges will not work. Here is a simplified version of what I'm doing in my code: using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using
