Application.DataTypeInfoFromDataType Method

Returns the DataTypeInfo object for the specified data type.

This API is not CLS-compliant. 

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

[CLSCompliantAttribute(false)]
public DataTypeInfo DataTypeInfoFromDataType(
	DataType dt
)

Parameters

dt
Type: Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType
The data type.

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.

Notes to Callers

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
