錯誤：錯誤的PInvoke簽名寫的鼠標點擊代碼

到的PInvoke函數「DoubleClickHover :: SendInput」呼叫具有不平衡堆棧。這很可能是因爲託管的PInvoke簽名與非託管目標籤名不匹配。檢查PInvoke簽名的調用約定和參數是否與目標非託管簽名相匹配。

請大家幫忙。謝謝你

[DllImport（「user32.dll」，SetLastError = true）] static extern uint SendInput（uint nInputs，INPUT [] pInputs，int cbSize）; – 2012-03-11 10:33:15

是的，你的SendInput的定義是錯誤的。第二個參數是一個指針的結構，你需要聲明爲通過引用傳遞：

[DllImport("user32.dll", SetLastError = true)] 
static extern uint SendInput(uint nInputs, ref INPUT pInputs, int cbSize);

或者你可以聲明pInputs爲數組（因爲這是它到底是什麼）：

[DllImport("user32.dll", SetLastError = true)] 
static extern uint SendInput(uint nInputs, INPUT[] pInputs, int cbSize);

使用「ref」有所幫助。謝謝你 – user1262117 2012-03-11 11:06:07
