SqlConnectionStringBuilder.DataSource Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets the name or network address of the instance of SQL Server to connect to.

Namespace: System.Data.SqlClient
Assembly: System.Data (in system.data.dll)

public string DataSource { get; set; 
/** @property */
public String get_DataSource ()

/** @property */
public void set_DataSource (String value)

public function get DataSource () : String

public function set DataSource (value : String)

Property Value

The value of the DataSource property, or String.Empty if none has been supplied.

This property corresponds to the "Data Source", "server", "address", "addr", and "network address" keys within the connection string. Regardless of which of these values has been supplied within the supplied connection string, the connection string created by the SqlConnectionStringBuilder will use the well-known "Data Source" key. If the value passed in is null when you try to set the property, the DataSource 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 demonstrates that the SqlConnectionStringBuilder class converts synonyms for the "Data Source" connection string key into the well-known key:

using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        SqlConnectionStringBuilder builder = new SqlConnectionStringBuilder(
            "Network Address=(local);Integrated Security=SSPI;" +
            "Initial Catalog=AdventureWorks");

        // Display the connection string, which should now 
        // contain the "Data Source" key, as opposed to the 
        // supplied "Network Address".
        Console.WriteLine(builder.ConnectionString);

        // Retrieve the DataSource property.
        Console.WriteLine("DataSource = " + builder.DataSource);

        Console.WriteLine("Press any key to continue.");
        Console.ReadLine();
