Gets or sets the name or network address of the instance of SQL Server to connect to.
(in System.Data.dll)
Visual Basic (Declaration)
Public Property DataSource As String
Dim instance As SqlConnectionStringBuilder
Dim value As String
value = instance.DataSource
instance.DataSource = value
public string DataSource { get; set; }
public:
property String^ DataSource {
String^ get ();
void set (String^ value);
}
public function get DataSource () : String
public function set DataSource (value : String)
Property Value
Type:
System..::.StringThe 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:
Imports System.Data.SqlClient
Module Module1
Sub Main()
Dim builder As _
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()
End Sub
End Module
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();
}
}
