In MSDN, the .NET's database connection string has a detailed description, I have some ways of code examples, and the meaning of each representative can be found in the MSDN. ADO.NET Database connection method (Microsoft is provided) Microsoft provides the following four database connection: System.Data.OleDb.OleDbConnectionSystem.Data.SqlClient.SqlConnectionSystem.Data.Odbc.OdbcConnectionSystem.Data.OracleClient.OracleConnection Here we have an example of the way in order to explain: System.Data. SqlClient.SqlConnection some common connection string (C # Code): SqlConnection conn = new SqlConnection ( "Server = (local); Integrated Security = SSPI; database = Pubs"); SqlConnection conn = new SqlConnection ( "server = (local) / NetSDK; database = pubs; Integrated Security = SSPI "); SqlConnection conn = new SqlConnection (" Data Source = localhost; Integrated Security = SSPI; Initial Catalog = Northwind; "); SqlConnection conn = new SqlConnection (" data source = ( local); initial catalog = xr; integrated security = SSPI; persist security info = False; workstation id = XURUI; packet size = 4096; "); SqlConnection myConn = new System.Data.SqlClient.SqlConnection (" Persist Security info = False ; Integrated security = sspi; database = northwind; server = mysqlserver "); SQLConnection conn = new SQLCO Nnection ("UID = SA; PWD = Passwords; Initial Catalog = Pubs; Data Source = 127.0.0.1; Connect Timeout = 900"); More String Connections Please see MSDN: http://msdn.microsoft.com/ library / default.asp url = / library / en-us / cpref / html / frlrfSystemDataSqlClientSqlConnectionClassConnectionStringTopic.asp System.Data.OleDb.OleDbConnection some common connection string (C # Code):?
