WPF继承窗口或控件

我是靠谱客的博主跳跃香烟，最近开发中收集的这篇文章主要介绍WPF继承窗口或控件，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

WPF自定义窗口基类时，窗口基类只定义.cs文件，xaml文件不定义。继承自定义窗口的类xaml文件的根节点就不再是<Window>，
而是自定义窗口类名（若自定义窗口与继承者不在同一个命名空间，还得加上命名空间），继承自定义窗口类后台代码也得修改为继承自自定义窗口
exp:

//继承Window类的自定义窗口类

namespace 
WPF_Study.Entity

{

using 
System.Windows;

public 
class 
WindowBase:Window

{

private 
const 
int 
Fixed_Width = 540;

private 
const 
int 
Fixed_Height = 350;

public 
WindowBase() : 
base
()

{

this
.MaxWidth = Fixed_Width;

this
.MaxHeight = Fixed_Height;

this
.MinWidth = Fixed_Width;

this
.MinHeight = Fixed_Height;

}

}

}

//继承自定义窗口

//xaml文件
