Application.DataTypeInfoFromDataType Method

This method lets you get data type information for a specific data type. For example, if you pass "DT_I4" in the dt parameter, the return value is the DataTypeInfo object that contains the enumeration name of "DT_I4" and the type name of "four-byte signed integer". This information is useful for displaying the type information in a user interface or error message. For more information about data types, see Integration Services Data Types.

This method requires the addition of the Microsoft.SqlServer.Dts.Runtime.Wrapper to the project. In the C# code example, the using directive has aliased this namespace with the variable, Wrapper.

The following code example retrieves the name of the type, DT_I4.

#region Using directives
using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime;
using Wrapper = Microsoft.SqlServer.Dts.Runtime.Wrapper;
#endregion

namespace Application_and_Package
{
    class PackageTest
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            DataTypeInfo dti = app.DataTypeInfoFromDataType(Wrapper.DataType.DT_I4);
           Console.WriteLine("DataType = " + dti.TypeName);
        }
    }
}

Sample Output:

DataType = four-byte signed integer
