[WinForm]WinForm跨线程UI操作常用控件类大全
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
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);帮助类源码
集合类(Invokes.cs)
