如果属性类型不是，则抛出异常DateTime。

Microsoft Word 仅存储自定义日期属性的日期部分（无时间）。

例子

展示如何创建包含日期和时间的自定义文档属性。

Document doc = new Document();

doc.CustomDocumentProperties.Add("AuthorizationDate", DateTime.Now);
DateTime authorizationDate = doc.CustomDocumentProperties["AuthorizationDate"].ToDateTime();
Console.WriteLine($"Document authorized on {authorizationDate}");

显示自定义文档属性的各种类型转换方法。

Document doc = new Document();
CustomDocumentProperties properties = doc.CustomDocumentProperties;

DateTime authDate = DateTime.Today;
properties.Add("Authorized", true);
properties.Add("Authorized By", "John Doe");
properties.Add("Authorized Date", authDate);
properties.Add("Authorized Revision", doc.BuiltInDocumentProperties.RevisionNumber);
properties.Add("Authorized Amount", 123.45);

Assert.AreEqual(true, properties["Authorized"].ToBool());
Assert.AreEqual("John Doe", properties["Authorized By"].ToString());
Assert.AreEqual(authDate, properties["Authorized Date"].ToDateTime());
Assert.AreEqual(1, properties["Authorized Revision"].ToInt());
Assert.AreEqual(123.45d, properties["Authorized Amount"].ToDouble());
