屬性

備註

FileNotFoundException 會使用其值為 0x80070002 HRESULT COR_E_FILENOTFOUND。FileNotFoundException uses the HRESULT COR_E_FILENOTFOUND which has the value 0x80070002.

如果您的程式碼並沒有PathDiscovery權限的錯誤訊息,此例外狀況可能只包含檔案或目錄的名稱,而不是完整路徑。If your code does not have PathDiscovery permission, the error message for this exception may only contain file or directory names instead of fully qualified paths.
