命名空间: Microsoft.Office.Server.ApplicationRegistry.Runtime
程序集: Microsoft.SharePoint.Portal （在 microsoft.sharepoint.portal.dll 中）

语法

声明
Function EntityAsDataRow ( _
    tableToAddRowTo As DataTable _
) As DataRow
用法
Dim instance As IEntityInstance
Dim tableToAddRowTo As DataTable
Dim returnValue As DataRow

returnValue = instance.EntityAsDataRow(tableToAddRowTo)

DataRow EntityAsDataRow (
    DataTable tableToAddRowTo
)

参数

  • tableToAddRowTo
    The DataTable object to add the entity instance as a row to.

返回值

A System.Data.DataRow object.

备注

The DataTable is a central object in the Microsoft ADO.NET library. It represents one table of in-memory data.

When entity instances are transformed into data rows in a data table, they lose the special semantics attached to them in the Business Data Catalog, such as the ability to call instance methods on them. Therefore, you should transform entity instances into data rows only if absolutely necessary. Avoid using ADO.NET adapters that convert Business Data Catalog return types for maximum performance.
