ServerDocument.Save 方法
保存使用 ServerDocument 类对文档所做的任何更改。
命名空间: Microsoft.VisualStudio.Tools.Applications
程序集: Microsoft.VisualStudio.Tools.Applications.ServerDocument(在 Microsoft.VisualStudio.Tools.Applications.ServerDocument.dll 中)
语法
声明
Public Sub Save
public void Save()
异常
异常 | 条件 |
---|---|
DocumentClosedException | ServerDocument 已关闭。 |
MissingHostItemIdException | CachedDataHostItem 的 Id 属性为 nullnull 引用(在 Visual Basic 中为 Nothing) 或为空。 |
MissingDataIdException | CachedDataItem 的 Id 属性为 nullnull 引用(在 Visual Basic 中为 Nothing) 或为空。 |
MissingTypeException | CachedDataItem 的 DataType 属性为 nullnull 引用(在 Visual Basic 中为 Nothing) 或为空。 |
备注
Save 方法保存对文档中的缓存数据或部署清单 URL 所做的任何更改。如果使用磁盘上的文档创建 ServerDocument 对象,则此方法将这些更改保存到磁盘中。如果使用内存中的文档创建 ServerDocument 对象,则此方法将这些更改保存到内存缓冲区中。
示例
下面的代码示例为指定的 Excel 工作簿创建一个新的 ServerDocument,使用 SerializeDataInstance 方法修改工作表中缓存的字符串的值,然后使用 Save 方法保存更改。
此示例需要:
在 ExcelWorkbook1 命名空间中有 Sheet1 类的 Excel 文档级自定义项,以及 Sheet1 类中名为 CachedString的缓存字符串。
控制台应用程序项目或某些其他非 Office 项目。
对下列程序集的引用:
