Ejemplo

The following code example iterates through the collection and prints the TypeEnumName and TypeName of each data type in SQL Server Integration Services (SSIS).

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;

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

            //Iterate over the collection, printing the values
            //of the properties.
            foreach (DataTypeInfo dInfo in dataInfos)
            {
                Console.WriteLine("TypeName: {0}, TypeEnumName: {1}", dInfo.TypeName, dInfo.TypeEnumName);
                //Console.WriteLine("TypeEnumName   {0}", dInfo.TypeEnumName);
            }
        }
    }
}

Imports System

Imports Microsoft.SqlServer.Dts.Runtime
 
Namespace DataTypeInfo_Properties
    Class Program
        Shared Sub Main(ByVal args() As String)
            'Create the DataTypeInfos collection.
            Dim dataInfos As DataTypeInfos =  New Application().DataTypeInfos 
 
            'Iterate over the collection, printing the values
            'of the properties.
            Dim dInfo As DataTypeInfo
            For Each dInfo In dataInfos
                Console.WriteLine("TypeName: {0}, TypeEnumName: {1}", dInfo.TypeName, dInfo.TypeEnumName)
                'Console.WriteLine("TypeEnumName   {0}", dInfo.TypeEnumName);
            Next
        End Sub
    End Class
End Namespace
