سلام دوستان
من تا به حال از این کانکشن استفاده میکردم مشکلی نداشتم
private SqlConnection _connection = new SqlConnection("Data Source=.;Initial Catalog=Cheque;integrated security=True;");
اما حالا میخوام از این استفاده کنم به خطا برخورد می کنم
private SqlConnection _connection = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirector y|\Cheque.mdf;integrated security=True;user instance = true;");
خطا :
Error :
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
