C - 手柄模拟鼠标控制(2)

/// [DllImport(\ public static extern int joyGetPosEx(int uJoyID, ref JOYINFOEX pji); 上面的两个API函数，我们可以从中任选一个，但joyGetPos函数只能取得1,2,3,4号四个按钮的状态。所以建议不用，下面只重讲解joyGetPosEx函数！ JOYINFO 与 JOYINFOEX 是属于结构体，它们的定义如下：

#region 游戏手柄的位置与按钮状态 ///

/// 游戏手柄的位置与按钮状态 ///

[StructLayout(LayoutKind.Sequential)] public struct JOYINFO { public int wXpos; public int wYpos; public int wZpos; public int wButtons; } ///

/// 游戏手柄的位置与按钮状态 ///

[StructLayout(LayoutKind.Sequential)] public struct JOYINFOEX { ///

public int dwFlags; ///

/// Current X-coordinate. ///

public int dwXpos; ///

/// Current Y-coordinate. ///

public int dwYpos; ///
