C#模擬實現鼠標自動點擊與消息發(fā)送功能

更新時間：2022年08月22日 14:52:53 作者：Csharp 小記

這篇文章主要為大家詳細介紹了C#如何利用windows api來模擬實現鼠標點擊、右擊、雙擊以及發(fā)送文本功能，文中的示例代碼講解詳細，感興趣的可以了解一下

實現功能

模擬鼠標點擊、文本輸入

開發(fā)環(huán)境

開發(fā)工具： Visual Studio 2013

.NET Framework版本：4.5

實現代碼

 #region 鼠標操作類型
 private const int MOUSEEVENTF_MOVE = 1;//鼠標移動

 private const int MOUSEEVENTF_RIGHTDOWN = 8;//按下鼠標右鍵
 
 private const int MOUSEEVENTF_RIGHTUP = 16;//抬起鼠標右鍵
