[System.CLSCompliant(false)]
public Microsoft.SqlServer.Dts.Runtime.DataTypeInfo DataTypeInfoFromDataType (Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType dt);
[<System.CLSCompliant(false)>]
member this.DataTypeInfoFromDataType : Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType -> Microsoft.SqlServer.Dts.Runtime.DataTypeInfo
Public Function DataTypeInfoFromDataType (dt As DataType) As DataTypeInfo

Parameters

Examples

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);  
        }  
    }  
}  
#Region "Using directives  
Imports System  
Imports System".Collections.Generic  
Imports System.Text  
Imports Microsoft.SqlServer.Dts.Runtime  
Imports Wrapper = Microsoft.SqlServer.Dts.Runtime.Wrapper  
#End Region  

Namespace Application_and_Package  
    Class PackageTest  
        Sub Main(ByVal args() As String)  
            Dim app As Application =  New Application()   
            Dim dti As DataTypeInfo =  app.DataTypeInfoFromDataType(Wrapper.DataType.DT_I4)   
           Console.WriteLine("DataType = " + dti.TypeName)  
        End Sub  
    End Class  
End Namespace  

Sample Output:

DataType = four-byte signed integer

Remarks

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.
