语法

声明
Public Overridable ReadOnly Property EntityAsDataTable As DataTable
用法
Dim instance As AbstractEntityInstance
Dim value As DataTable

value = instance.EntityAsDataTable

public virtual DataTable EntityAsDataTable { get; }

属性值

A DataTable object with one row data.

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.
