Is there any connection string parser in C#?

Question

I have a connection string and I want to be able to peek out for example \"Data Source\". Is there a parser, or do I have to search the string?

Answer 1

Yes , You can do this using ConnectionStringBuilder Classes. Here is the list of available DbConnectionStringBuilder implementations for standard data providers:

System.Data.Odbc.OdbcConnectionStringBuilder
System.Data.OleDb.OleDbConnectionStringBuilder
System.Data.OracleClient.OracleConnectionStringBuilder
System.Data.SqlClient.SqlConnectionStringBuilder

here are sample example of parse connection string and display it's elements.

 string conString = @"Data Source=.\sqlexpress;" +
                        "Database=Northwind;Integrated Security=SSPI;" +
                        "Min Pool Size=5;Max Pool Size=15;Connection Reset=True;" +
                        "Connection Lifetime=600;";
    // Parse the SQL Server connection string and display it's properties

    SqlConnectionStringBuilder objSB1 = new SqlConnectionStringBuilder(conString);
    Response.Write("Parsed SQL Connection String Parameters:");
    Response.Write(" 
  Database Source = " + objSB1.DataSource);
    Response.Write(" 
  Database = " + objSB1.InitialCatalog);
    Response.Write(" 
  Use Integrated Security = " + objSB1.IntegratedSecurity);
    Response.Write(" 
  Min Pool Size = " + objSB1.MinPoolSize);
    Response.Write(" 
  Max Pool Size = " + objSB1.MaxPoolSize);
    Response.Write(" 
  Lifetime = " + objSB1.LoadBalanceTimeout);
