傳回布林值，指出指定的資料夾是否已存在於 SQL Server 的實例上。

public:
 bool FolderExistsOnSqlServer(System::String ^ strFolderName, System::String ^ strServerName, System::String ^ strServerUserName, System::String ^ strServerPassword);

public bool FolderExistsOnSqlServer (string strFolderName, string strServerName, string strServerUserName, string strServerPassword);

member this.FolderExistsOnSqlServer : string * string * string * string -> bool

Public Function FolderExistsOnSqlServer (strFolderName As String, strServerName As String, strServerUserName As String, strServerPassword As String) As Boolean

參數

strFolderName: String

您要尋找的資料夾。

strServerName: String

要搜尋封裝的 SQL Server 執行個體名稱。

strServerUserName: String

要針對 SQL Server 執行個體驗證的使用者名稱。

strServerPassword: String

給定 strServerUserName 的密碼。

傳回

Boolean

如果資料夾存在於指定的 SQL Server 實例上，則為 true。如果資料夾不存在，則為 false。

範例

下列程式碼範例會在上建立資料夾 SQL Server 、將它重新命名，然後將它移除。它也會使用來確認資料夾是否存在 FolderExistsOnSqlServer 。
