我试图在从我们的系统发送之前从 word 文件中删除敏感信息。下面是要发送的文件中的自定义属性示例。我想删除 filePath 和 templateFilePath 的内容。

我从 Open XML SDK 生产力工具获得了这段代码:
private static void ChangeCustomFilePropertiesPart(CustomFilePropertiesPart customFilePropertiesPart)
{
CustomProperties.Properties properties = customFilePropertiesPart.Properties;
CustomProperties.CustomDocumentProperty customDocumentProperty1 = properties.Elements<CustomProperties.CustomDocumentProperty>().ElementAt(4);
CustomProperties.CustomDocumentProperty customDocumentProperty2 = properties.Elements<CustomProperties.CustomDocumentProperty>().ElementAt(5);
VariantTypes.VTLPWSTR vTLPWSTR1 = customDocumentProperty1.GetFirstChild<VariantTypes.VTLPWSTR>();
vTLPWSTR1.Text = "";
VariantTypes.VTLPWSTR vTLPWSTR2 = customDocumentProperty2.GetFirstChild<VariantTypes.VTLPWSTR>();
vTLPWSTR2.Text = "";
}
但是我不能相信我要删除的属性是数字 4 和 5,所以我必须在删除文本之前通过 name 属性找到它们。谁能帮我?我想以某种方式使用 linq 或 Open XML SDK。
谢谢!
