前言

在C#开发的WinForm窗体程序开发的时候,经常会使用多线程处理一些比较耗时之类的操作。不过会有一个问题:就是涉及到跨线程操作UI元素。
相信才开始接触的人一定会遇上这个问题。

为了解决这个问题,可以通过委托来实现。

我为了后期使用更加方便,就将常用的几个控件(TextBox、Label、CheckBox、RadioButton、ProgressBar)UI操作进行了封装,源码可以在github上查看:GitHub仓库地址
源码在github仓库中的XY.WINUI.ControlEx.InvokeEx文件夹中

测试窗体

使用示例

在测试项目中有使用的方法,这里只做简单介绍。
调用方法在Invokes类中,也可以使用单独的类调用。

例如:在窗体中为tbName的TextBox设置和获取值

//首先,使用命名空间
using XY.WINUI.ControlEx.InvokeEx;

//第一种
//设置TextBox的值
Invokes.SetTextBoxText(tbName,"TextBox文本");
//获取TextBox的值
string value = Invokes.GetTextBoxText(tbName);


//第二种
//设置TextBox的值
TextBoxInvoke.SetTextBoxText(tbName,"TextBox文本");
//获取TextBox的值
string value = TextBoxInvoke.GetTextBoxText(tbName);
