OleDbConnectionStringBuilder.DataSource Property

Gets or sets the name of the data source to connect to.

Namespace:  System.Data.OleDb
Assembly:  System.Data (in System.Data.dll)

public string DataSource { get; set; }

Property Value

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

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. This property corresponds to the "Data Source" key within the connection string.

The following example console application creates a new OleDbConnectionStringBuilder instance, and then sets the DataSource and Provider properties. Finally, the example creates a new OleDbConnection instance, and uses that object to connect to the indicated data store.

using System.Data.OleDb;

class Program
    static void Main()
        OleDbConnectionStringBuilder builder =
            new OleDbConnectionStringBuilder();
        builder.DataSource = @"C:\Sample.mdb";
        builder.Provider = "Microsoft.Jet.Oledb.4.0";

        // This sample assumes that you have a database named 
        // C:\Sample.mdb available. 
        using (OleDbConnection connection = new
                // Do something with the database here.
            catch (Exception ex)

        Console.WriteLine("Press Enter to finish.");
