public:
 bool ExistsOnSqlServer(System::String ^ packagePath, System::String ^ serverName, System::String ^ serverUserName, System::String ^ serverPassword);

public bool ExistsOnSqlServer(string packagePath, string serverName, string serverUserName, string serverPassword);

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

Public Function ExistsOnSqlServer (packagePath As String, serverName As String, serverUserName As String, serverPassword As String) As Boolean

Параметры

packagePath

String

serverName

String

Название экземпляра SQL Server для поиска пакета.

serverUserName

String

Имя пользователя для аутентификации в экземпляре SQL Server.

Примеры

Следующий пример кода создаёт папку SQL Server, проверяет её существование, затем удаляет папку и повторно проверяет её существование. Также сохраняется пакет и проверяется, что пакет был сохранён с помощью этого ExistsOnSqlServer метода.
