我跟着a tutorial on Video Player。訪問已發佈應用程序中的資源
這很好，但我想象的是一種不同的情況。
我需要嵌入資源文件中的一些視頻，並根據用戶輸入動態更改視頻。 我使用switch語句在Visual Studio 2010中管理了這個運行。 但我必須在資源文件中指定該視頻的路徑。對於如：
System.NullReferenceException: Object reference not set to an instance of an object.
at VideoPlayer.Form1.button2_Click(Object sender, EventArgs e)
at System.Windows.Forms.Control.OnClick(EventArgs e)
at System.Windows.Forms.Button.OnClick(EventArgs e).............
看來，視頻文件沒有包含在應用程序：
case 1 : video = new Video("..//..//Resources//The video name");
但是當我發佈使用點擊一次嚮導此應用程序，最終應用在異常結束。 但是，當我看到安裝程序文件夾，清晰的外觀顯示，有一個文件名爲VideoPlayer.exe.deploy它通常是59MB這些文件沒有任何資源是輕的加權...
它肯定包含視頻文件。但我無法訪問該文件。
如何訪問？
請幫我...
在此先感謝:-)
至於問一些用戶，我張貼在C＃.NET整個代碼：

而且我認爲一個屏幕截圖可能是一些信息：
它工作正常，在調試模式下.....但是，一旦我使用點擊一次安裝程序安裝它，它崩潰成例外。如何使用DEPLOY文件中的資源管理相同的內容？
難道你只是混淆了斜槓和反斜槓嗎？ – svick
不...實際上我發佈的代碼在Visual Studio下「調試」解決方案時運行得非常好。注意：實際上我有比調試文件夾高兩級的Resources文件夾。因此，斜槓。但是，當我使用Click Once Application安裝應用程序時，它給了我提到的例外。我認爲這是因爲一旦我們在我們的Windows機器上安裝了應用程序，工作組件就不一樣了。另外安裝的文件系統也不同。任何人都可以幫助我在這個?????????請...... – killerCoder
