C# 连接SQLSERVER数据库 连接字符串

C# 连接SQLSERVER数据库 连接字符串

一:C# 连接SQL数据库 Data Source=myServerAddress;Initial Catalog=myDataBase;User Id=myUsername;Password=myPassword; Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=myDataBase;User ID=myUsername;Password=myPassword; Server=myServerAddress;Database=myDataBase;User ID=myUsername;Password=myPassword;Trusted_Connection=False; Server=myServerAddress;Database=myDataBase;Trusted_Connection=True; Server=myServerName\\theInstanceName;Database=myDataBase;Trusted_Connection=True; Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;

1:Integrated Security参数 当设置Integrated Security为 True 的时候,连接语句前面的 UserID, PW 是不起作用的,即采用windows身份验证模式。 只有设置为 False 或省略该项的时候,才按照 UserID, PW 来连接。 Integrated Security 还可以设置为:sspi ,相当于 True,建议用这个代替 True。 Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI; Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=true; Data Source=myServerAddress;Initial Catalog=myDataBase;;User ID=myUsername;Password=myPasswordIntegrated Security=false;

2:参数Trusted_Connection Trusted_Connection=true,将使用当前的 Windows 帐户凭据进行身份验证 Trusted_Connection=false;将不采用信任连接方式(也即不采用Windows验证方式),而改由SQL Server 2000验证方式 Server=myServerAddress;Database=myDataBase;User ID=myUsername;Password=myPassword;Trusted_Connection=false; Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

3:Initial Catalog是你要连接的数据库的名字

4:WINCE连接 Data Source=myServerAddress;Initial Catalog=myDataBase;Integrated Security=SSPI;User ID=myDomain\\myUsername;Password=myPassword;

二:可以利用SqlConnectionStringBuilder,这样不必去记住名称。 SqlConnectionStringBuilder scsb = new SqlConnectionStringBuilder(); scsb.DataSource = @”(local)\\SQLExpress”; scsb.IntegratedSecurity = true; scsb.InitialCatalog = “Northwind”; SqlConnection myConnection = new SqlConnection(scsb.ConnectionString);

三:可以利用属性中的Setting来自动设置连接字符串 1:在type中选择 (connection string), 2:在DataSouce中选择数据源,然后再Server中输入服务器名,本地用(local)\\SQLExpress 3:选择登陆验证方式,本次选Windows验证(即信任连接Integrated Security=True) 4:选择数据库名,确认即可 Data Source=(local)\\SQLExpress;Initial Catalog=Northwind;Integrated Security=True server = .\\sqlexpress;integrated security = true;database = northwind
