    isCached As Boolean, _
    isStatic As Boolean _
) As Method
用法
Dim instance As MethodCollection
Dim name As String
Dim isCached As Boolean
Dim isStatic As Boolean
Dim returnValue As Method

returnValue = instance.Create(name, isCached, isStatic)

public Method Create (
    string name,
    bool isCached,
    bool isStatic
)

参数

• name
  The name of the method.

• isCached
  true if cached; otherwise, false.

• isStatic
  true if the method is static; false if not.

返回值

A Method object.

示例

The following code example shows how to create a method, complete with method instances, filter descriptors, default values, and type descriptors, for the ProductModel entity in the AdventureWorks2000 database.

Prerequisites

• Ensure a Shared Service Provider is already created.

• Create an LobSystem instance and set connection parameters as shown in 如何：使用管理对象模型创建 LobSystem.

• Create the ProductModel entity as shown in 如何：使用管理对象模型创建实体

• Replace the constant value EnterYourSSPNameHere in the code with the name of your Shared Resource Provider.
