Comentários

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 Tipos de dados do Integration Services.

Observações para chamadores

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.

Exemplos

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
