我試圖使該計算保持時間和新聞界碼/按鍵的釋放時間通過鍵盤輸入。意外的文本（System.Int32 []）
hold time = keyup(i) - keydown(i+1)
release_press time = keydown(i+1) - keyup(i)
press_press time = keydown(i+1) - keydown(i)
release_release time = keyup(i+1) - keyup(i)
，這是我的代碼，既沒有錯誤，也沒有警告......但是當我運行它，我得到（System.Int32[]）在文本框中，其中並同時按下/釋放時間應該展出。我不知道爲什麼我會收到錯誤或錯誤在哪裏。

這是非常* *醜陋的代碼。至少應該爲變量使用描述性名稱。你可能沒有甚至需要在這裏後，如果'A'被評爲像'KeyDurations'。 // MSDN： – Bobson 2013-05-08 16:24:45
