+# 基本用法
+
+1. 发送鼠标事件
+
+```c#
+Mouse.Event(point:Mouse.Point(100,100),
+            button:Mouse.Button.Left,
+            action:Mouse.Action.Click);
+//button枚举值：Left，Right，Middle
+//action枚举值：Click，Up，Down
+```
+
+2. 获得当前鼠标位置
+
+```c#
+Point p=Mouse.Location();
+```
+
+3. 保存当前鼠标位置
+
+```c#
+Mouse.SaveLocation();
+```
+
+4. 恢复之前保存的鼠标位置
+
+```c#
+Mouse.RestoreLocation();
+```
+
+# 备注
+
+```c#
+//Point 为 System.Drawing.Point 类
+//Mouse 中实现了一个静态方法
+public static Point Mouse.Point(int x,int y);
+//可以返回一个 Point 类来实现更优雅的调用。
+```
