Application.DataTypeInfoFromDataType Method

Returns the DataTypeInfo object for the specified data type. This method is not CLS-compliant.

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

public DataTypeInfo DataTypeInfoFromDataType (
	DataType dt
/** @attribute CLSCompliantAttribute(false) */ 
public DataTypeInfo DataTypeInfoFromDataType (
	DataType dt
public function DataTypeInfoFromDataType (
	dt : DataType
) : DataTypeInfo



The data type.

Return Value

A DataTypeInfo object.

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;

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

Any public static (Shared in Microsoft Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
