连接字符串 ASP.NET

Question

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlDataSource1"].ToString());


  <connectionStrings>
    <add name="SqlDataSource1"
         connectionString="Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=SqlDataSource3;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\SqlDataSource3.mdf"
         providerName="System.Data.SqlClient"/>
  </connectionStrings>

Should that work now?

Is at ConnectionStrings["XXX"] has to be placed Name or Initial Catalog of connectionStrings?

Answer 1

As shown on this page , the index value is the name of the connection string. Therefore your code is correct.

Now wondering why you have posted the question. Does your code not work?

Answer 2

Try this:

<add name="SqlDataSource1" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;Initial Catalog=SqlDataSource3;Integrated Security=True"/>

and then:

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["SqlDataSource1"].ConnectionString);

Hope this helps.
