Question

一个简单的赋值，如下面用C＃编写的控制台应用程序：

workbook.CustomDocumentProperties.Item["PropertyName"] = "Property Value";

产生以下错误：

{"Value does not fall within the expected range."}
    Data: {System.Collections.ListDictionaryInternal}
    HResult: -2147024809

我首先尝试在Add属性上调用CustomDocumentProperties方法，如下所示：

workbook.CustomDocumentProperties.Add("PropertyName", "Property Value");

当失败时，我回顾了the documentation，其评论如下（强调我的）：

此属性返回自定义文档的整个集合属性。 使用 Microsoft.Office.Core.DocumentProperties.Item（System.Object）属性 返回集合中的单个成员（a Microsoft.Office.Core.DocumentProperties对象）通过指定属性的名称或集合索引（作为数字）。

Answer 1

在Word中（可能在Excel中），如果该属性不存在，则可以使用CustomDocumentProperties.Add方法进行设置。但是，您需要确保传递一个Type参数，在您的情况下，该参数将是MsoDocProperties.msoPropertyTypeString。

希望这有帮助。

写入Workbook.CustomDocumentProperties时，“值不在预期范围内”
