DataTypeInfo.TypeEnumName Property

Returns the symbolic name of the data type. This field is read-only.

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

public string TypeEnumName { get; }

Property Value

Type: System.String
A string that contains the symbolic name of the data type.

This returns the short name for the data type. For example, this property returns DT_R4 for a float.

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);
