DataTypeInfos.Item Property

Returns a DataTypeInfo object from the collection.

Namespace:  Microsoft.SqlServer.Dts.Runtime
Assembly:  Microsoft.SqlServer.ManagedDTS (in Microsoft.SqlServer.ManagedDTS.dll)

Syntax

'Declaration
Public ReadOnly Default Property Item ( _
    index As Object _
) As DataTypeInfo
    Get
'Usage
Dim instance As DataTypeInfos
Dim index As Object
Dim value As DataTypeInfo

value = instance(index)

public DataTypeInfo this[
    Object index
] { get; }

public:
property DataTypeInfo^ default[Object^ index] {
    DataTypeInfo^ get (Object^ index);
}

member Item : DataTypeInfo

JScript supports the use of indexed properties, but not the declaration of new ones.

Parameters

Remarks

If the call to the Contains method returns true, you can access the specified element in the collection by using the syntax DataTupeInfos[index]. If the Contains method returns false, this property throws an exception. In C#, this property is the indexer for the DataTypeInfos class.

Examples

The following code sample retrieves an item from the collection using two methods. The first method uses the dataInfos[0] syntax to retrieve the entire object located in the first position of the collection and place it in the dtInfo object. After this is done you can retrieve all properties from the dtInfo object as usual. The second method demonstrates how to retrieve a specific property from the first object in the collection.

{
    class Program
    {
        static void Main(string[] args)
        {
            //Create the DataTypeInfos collection.
            DataTypeInfos dataInfos = new Application().DataTypeInfos;

            //Using the Item method syntax of [x], obtain the first entry.
            DataTypeInfo dtInfo = dataInfos[0];
            String nameOfFirstItem = dataInfos[0].TypeName;

            //Print the name of the task object located at position [0].
            Console.WriteLine("The TypeEnumName of the first item is: {0}", dtInfo.TypeEnumName);
            Console.WriteLine("The TypeName of the first task is: {0}", nameOfFirstItem);
        }
    }
}

            Console.WriteLine("The TypeName of the first task is: {0}", nameOfFirstItem)
        End Sub

Sample Output:

The TypeEnumName of the first item is: DT_R4

The TypeName of the first task is: float
