问题回答

您不得在我国家中指定数据库名称。

InitialCatalog = [databaseName] 

你的纽带应该像这样看待。

data source=[ServerName];Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=[DatabaseName];

我想myConnection,已经在连接地标上注明了缺省词(即数据库),因此,你无需使用<代码><<>use。

无;我的Connection Object s connectionstring应当界定哪些数据库需要使用,以及服务器和标识信息。

所有这一切都应符合我的“能力”变量,因为我假定其中含有连接线。

虽然你可能希望用数据Adapter呼吁

using(SqlDataAdapter dap = new SqlDataAdapter("select * from some table", myConnection)
{
    //do stuff with dap here 
}//dispose of dap

由于它确实继承了可适用的身份证明。

您的联系可以告诉它哪些数据库可以连接。

connectionString = "Data Source=SERVERNAME; Initial Catalog=DATABASENAME; Integrated Security=SSPI;";

这将通过验证窗口与服务器和数据库建立联系。
