一段引发错误的代码,请大家看看.

C# code

Point ptClient = this.m_panel.Invoke(this.GetClientPos, new object[] {ptScreen});

报错:

Cannot implicitly convert type 'object' to 'System.Drawing.Point'. An explicit conversion exists (are you missing a cast?)

[解决办法]
试试
Point ptClient = (Point)this.m_panel.Invoke(this.GetClientPos, new object[] {ptScreen});

[解决办法]
强制类型转换！
[解决办法]
类型转换就行了
