Question

我在文档库中有一个现有文档，我试图用代码覆盖该文件：

byte[] data = ...
SPListItem li = ...
li.File.SaveBinary(data);

当我运行此代码时，我得到：

Microsoft.SharePoint.SPException: The security validation for this page is invalid. Click Back in your Web browser, refresh the page, and try your operation again. ---> System.Runtime.InteropServices.COMException (0x8102006D): The security validation for this page is invalid.

    at Microsoft.SharePoint.SPFile.SaveBinary(Byte[] file)
    at TestClass.UploadFile()

我在与sharepoint在同一站点中托管的表单上运行此代码，运行代码的用户可以手动上传文件。我需要先删除文件吗？看看吧？

Answer 1

尝试此操作来修复它：

SPSecurity.RunWithElevatedPrivileges(delegate
{
  using (SPSite elevSite = new SPSite(currentWeb.Site.ID))
  {
    using (SPWeb elevWeb = elevSite.OpenWeb(currentWeb.ID))
    {
      elevWeb.AllowUnsafeUpdates = true;
      // ...
    }
  }
}

Answer 2

我明白了。我在SPSecurity.RunWithElevatedPrivileges块中进行调用，导致它失败。我发现这很有趣，因为你会认为使用已经过时的权限运行会有更多的访问权限。

Answer 3

尝试此操作以删除错误“此页面的安全验证无效。在Web浏览器中单击”返回“，刷新页面，然后再次尝试操作。”
