从内存中加载的元数据构造 EntityConnection

命名空间：  System.Data.Entity.Core.EntityClient
程序集：  EntityFramework（在 EntityFramework.dll 中）

语法

声明
<SuppressMessageAttribute("Microsoft.Reliability", "CA2000:DisposeObjectsBeforeLosingScope", Justification := "Object is in fact passed to property of the class and gets Disposed properly in the Dispose() method.")> _
Public Sub New ( _
    workspace As MetadataWorkspace, _
    connection As DbConnection, _
    entityConnectionOwnsStoreConnection As Boolean _
)
用法
Dim workspace As MetadataWorkspace 
Dim connection As DbConnection 
Dim entityConnectionOwnsStoreConnection As Boolean 

Dim instance As New EntityConnection(workspace, _
    connection, entityConnectionOwnsStoreConnection)

[SuppressMessageAttribute("Microsoft.Reliability", "CA2000:DisposeObjectsBeforeLosingScope", Justification = "Object is in fact passed to property of the class and gets Disposed properly in the Dispose() method.")]
public EntityConnection(
    MetadataWorkspace workspace,
    DbConnection connection,
    bool entityConnectionOwnsStoreConnection
)

[SuppressMessageAttribute(L"Microsoft.Reliability", L"CA2000:DisposeObjectsBeforeLosingScope", Justification = L"Object is in fact passed to property of the class and gets Disposed properly in the Dispose() method.")]
public:
EntityConnection(
    MetadataWorkspace^ workspace, 
    DbConnection^ connection, 
    bool entityConnectionOwnsStoreConnection
)

[<SuppressMessageAttribute("Microsoft.Reliability", "CA2000:DisposeObjectsBeforeLosingScope", Justification = "Object is in fact passed to property of the class and gets Disposed properly in the Dispose() method.")>]
new : 
        workspace:MetadataWorkspace * 
        connection:DbConnection * 
        entityConnectionOwnsStoreConnection:bool -> EntityConnection

public function EntityConnection(
    workspace : MetadataWorkspace, 
    connection : DbConnection, 
    entityConnectionOwnsStoreConnection : boolean
)

参数

  • entityConnectionOwnsStoreConnection
    类型：System.Boolean
    如果设置为 true，则释放实体连接时将释放该存储连接；否则调用方必须释放该存储连接。
