SqlConnectionStringBuilder.AttachDBFilename Property
Assembly: System.Data (in system.data.dll)
/** @property */ public String get_AttachDBFilename () /** @property */ public void set_AttachDBFilename (String value)
public function get AttachDBFilename () : String public function set AttachDBFilename (value : String)
Property Value
The value of the AttachDBFileName property, or String.Empty if no value has been supplied.This property corresponds to the "AttachDBFilename", "extended properties", and "initial file name" keys within the connection string. If the value passed in is null when you try to set the property, the AttachDBFilename property is reset. If the value has not been set and the developer tries to retrieve the property, the return value is String.Empty.
The following example creates a new SqlConnectionStringBuilder instance, and sets the AttachDBFilename property in order to specify the name of an attached data file.
using System.Data.SqlClient; class Program { static void Main() { try { string connectString = "Server=(local);" + "Integrated Security=true"; SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(connectString); Console.WriteLine("Original: " + builder.ConnectionString); Console.WriteLine("AttachDBFileName={0", builder.AttachDBFilename); builder.AttachDBFilename = @"C:\MyDatabase.mdf"; Console.WriteLine("Modified: " + builder.ConnectionString); using (SqlConnection connection = new SqlConnection(builder.ConnectionString)) { connection.Open(); // Now use the open connection. Console.WriteLine("Database = " + connection.Database); Console.WriteLine("Press any key to finish."); Console.ReadLine(); catch (Exception ex) { Console.WriteLine(ex.Message);
