- dt
Тип: Microsoft.SqlServer.Dts.Runtime.Wrapper.DataType
The data type.
Возвращаемое значение
Тип: Microsoft.SqlServer.Dts.Runtime.DataTypeInfo
A DataTypeInfo object.
Замечания
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 Типы данных служб Integration Services.
Примечания по вызову
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.
Примеры
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
