ReplicationObject.LoadProperties 方法

定义

命名空间:

Microsoft.SqlServer.Replication

程序集:

Microsoft.SqlServer.Rmo.dll

从服务器加载现有对象的属性。

public:
 bool LoadProperties();

public bool LoadProperties ();

member this.LoadProperties : unit -> bool

Public Function LoadProperties () As Boolean

返回

Boolean

一个 Boolean 值。 如果true存在该对象，则存在于 Microsoft SQL Server实例上。 如果false不存在该对象，则SQL Server实例上不存在该对象。

示例

// Define the server, database, and publication names
string publisherName = publisherInstance;
string publicationName = "AdvWorksSalesOrdersMerge";
string publicationDbName = "AdventureWorks2012";

    conn.Connect();

    // Set the required properties for the publication.
    publication = new MergePublication();
    publication.ConnectionContext = conn;
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;


    // If we can't get the properties for this merge publication, then throw an application exception.

注解

如果属性已加载，则不会重新加载它们。 如果它们不是当前属性，请在对象上调用 Refresh 该方法以刷新属性。

如果缺少有关此对象的足够信息，则会引发异常。 如果服务器上不存在该对象，该方法将 false返回 。 否则，将加载属性并返回 true方法。
