CSOM：如何将文档从一个文档库复制到另一个文档库？

Question

我需要将满足特定条件（文档的审批状态 = 已批准）的所有文档复制到 SharePoint Online 中的存档文档库。我正在遍历所有站点并使用 CAML 查询过滤出批准的文档，但我不知道如何使用 CSOM C# 将此文档复制到不同的库位置。另外，我需要替换文档，以防它已经存在于存档库中。

注意：存档库位于不同的网站集中。

非常感谢任何帮助。提前谢谢你。

请参考以下代码

        var srcUrl = "srcurl";
        var destUrl = "destUrl ";
        var srcLibrary = "srcLibrary";
        var destLibrary = "destLibrary";

        ClientContext destContext = new ClientContext(destUrl);
        ClientContext srcContext = new ClientContext(srcUrl);

        var strPassword = "password";
        SecureString secureString = new SecureString();
        strPassword.ToList().ForEach(secureString.AppendChar);
        destContext.Credentials = new SharePointOnlineCredentials("xxx@xxx.onmicrosoft.com", secureString);
        srcContext.Credentials = new SharePointOnlineCredentials("xxx@xxx.onmicrosoft.com", secureString);


        Web srcWeb = srcContext.Web;

        List srcList = srcWeb.Lists.GetByTitle(srcLibrary);

        Web destWeb = destContext.Web;

        destContext.Load(destWeb);

        destContext.ExecuteQuery();
        try
        {
            Microsoft.SharePoint.Client.File file = srcContext.Web.GetFileByServerRelativeUrl("filepath");
            srcContext.Load(file);
            srcContext.ExecuteQuery();
            string location = destWeb.ServerRelativeUrl.TrimEnd('/') + "/" + destLibrary.Replace(" ", "") + "/" + file.Name;
            FileInformation fileInfo = Microsoft.SharePoint.Client.File.OpenBinaryDirect(srcContext, file.ServerRelativeUrl);
            Microsoft.SharePoint.Client.File.SaveBinaryDirect(destContext, location, fileInfo.Stream, true);
        }

        catch (Exception ex)
        {
            throw ex;
        }
