OdbcConnectionStringBuilder.Item Property

Gets or sets the value associated with the specified key. In C#, this property is the indexer.

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

public override Object this[
	string keyword
] { get; set; }

Parameters

keyword
Type: System.String

The key of the item to get or set.

Property Value

Type: System.Object
The value associated with the specified key.

ExceptionCondition
ArgumentException

The connection string is incorrectly formatted (perhaps missing the required "=" within a key/value pair).

ArgumentNullException

keyword is a null reference (Nothing in Visual Basic).

When you set this property, if the specified key already exists in the dictionary, the value is replaced; otherwise, a new element is created.

The following code, in a console application, creates a new OdbcConnectionStringBuilder and adds key/value pairs to its connection string, using the Item property.

using System.Data.Odbc;


class Program
{
    static void Main()
    {
        OdbcConnectionStringBuilder builder = 
            new OdbcConnectionStringBuilder();
        // Set up a connection string for a text file.
        builder["Driver"] = "Microsoft Text Driver (*.txt; *.csv)";
        builder["dbq"] = "C:\\TextFilesFolder";
        builder["Extension"] = "asc,csv,tab,txt";

        // Overwrite the existing value for the dbq value,  
        // because it already exists within the collection.
        builder["dbq"] = "D:\\";

        Console.WriteLine(builder.ConnectionString);
        Console.WriteLine();
        Console.WriteLine("Press Enter to continue.");
        Console.ReadLine();
    }
}
