如何查看和修改发布属性（RMO 编程）

可使用复制管理对象 (RMO) 以编程方式修改发布和访问其属性。查看或修改发布属性所使用的 RMO 类取决于发布的类型。

查看或修改快照发布或事务发布的属性

使用 ServerConnection 类创建与发布服务器的连接。
创建 TransPublication 类的实例，为发布设置 Name 和 DatabaseName 属性并将 ConnectionContext 属性设置为步骤 1 中创建的连接。
调用 LoadProperties 方法以获取对象的属性。如果此方法返回 false，则表示步骤 2 中定义的发布属性不正确，或者表示该发布不存在。
（可选）若要更改属性，为一个或多个可设置的属性设置新值。使用逻辑 AND 运算符（在 Microsoft Visual C# 中为 &，在 Microsoft Visual Basic 中为 And）可确定是否为 Attributes 属性设置了给定的 PublicationAttributes 值。使用逻辑 OR 运算符（在 Visual C# 中为 |，在 Visual Basic 中为 Or）和逻辑异或运算符（在 Visual C# 中为 ^，在 Visual Basic 中为 Xor）可更改 Attributes 属性的 PublicationAttributes 值。
（可选）如果已将 CachePropertyChanges 的值指定为 true，则调用 CommitPropertyChanges 方法以在服务器上提交更改。如果已将 CachePropertyChanges 的值指定为 false（默认值），则会立即将更改发送到服务器。

查看或修改合并发布的属性

使用 ServerConnection 类创建与发布服务器的连接。
创建 MergePublication 类的实例，为发布设置 Name 和 DatabaseName 属性并将 ConnectionContext 属性设置为在步骤 1 中创建的连接。
调用 LoadProperties 方法以获取对象的属性。如果此方法返回 false，则表示步骤 2 中定义的发布属性不正确，或者表示该发布不存在。
（可选）若要更改属性，为一个或多个可设置的属性设置新值。使用逻辑 AND 运算符（在 Visual C# 中为 &，在 Visual Basic 中为 And）可确定是否为 Attributes 属性设置了给定的 PublicationAttributes 值。使用逻辑 OR 运算符（在 Visual C# 中为 |，在 Visual Basic 中为 Or）和逻辑异或运算符（在 Visual C# 中为 ^，在 Visual Basic 中为 Xor）可更改 Attributes 属性的 PublicationAttributes 值。
（可选）如果已将 CachePropertyChanges 的值指定为 true，则调用 CommitPropertyChanges 方法以在服务器上提交更改。如果已将 CachePropertyChanges 的值指定为 false（默认值），则会立即将更改发送到服务器。

示例

该示例设置事务发布的发布属性。这些更改将被缓存，直至将其显式发送到服务器。

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

            TransPublication publication;

            // Create a connection to the Publisher.
            ServerConnection conn = new ServerConnection(publisherName);

            try
            {
                // Connect to the Publisher.
                conn.Connect();

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

                // Explicitly enable caching of property changes on this object.
                publication.CachePropertyChanges = true;

                // If we can't get the properties for this publication, 
                // throw an application exception.
                if (publication.LoadProperties())
                {

                    // for pull subscriptions.
                    if ((publication.Attributes & PublicationAttributes.AllowPull) != 0)
                    {
                        publication.Attributes ^= PublicationAttributes.AllowPull;
                    }
                    if ((publication.Attributes & PublicationAttributes.AllowPush) == 0)
                    {
                        publication.Attributes |= PublicationAttributes.AllowPush;
                    }

                    // Send changes to the server.
                    publication.CommitPropertyChanges();
                }
                else
                {
                    throw new ApplicationException(String.Format(
