OleDbFactory.Instance 字段

定义

命名空间:

System.Data.OleDb

程序集:

System.Data.dll

获取 . 的 OleDbFactory实例。 这可用于检索强类型数据对象。

public: static initonly System::Data::OleDb::OleDbFactory ^ Instance;

public static readonly System.Data.OleDb.OleDbFactory Instance;

 staticval mutable Instance : System.Data.OleDb.OleDbFactory

Public Shared ReadOnly Instance As OleDbFactory 

字段值

OleDbFactory

示例

以下代码片段使用 Instance 字段检索 OleDbFactory 实例，然后返回强类型 DbCommand 实例：

Dim newFactory As OleDbFactory = OleDbFactory.Instance
Dim cmd As DbCommand = newFactory.CreateCommand()

OleDbFactory newFactory = OleDbFactory.Instance;
DbCommand cmd = newFactory.CreateCommand();
