如何使用CamlQuery按名称获取sharepoint文件夹

Question

所以我需要从crm重命名插件中的sharepoint文件夹。文件夹的名称是联系人的全名，但是如果名称中有错字，则还需要一个插件来更改共享点中的文件夹名称。我找到了一种方法来执行此操作，但是要执行此操作，我需要获取该文件夹，而我正在尝试使用CamlQuery进行此操作。（2010年是一个共享点）

这是我要获取文件夹的操作：

            ClientContext clientContext = new ClientContext(siteUrl);
            clientContext.Credentials = new NetworkCredential(login, password);
            Web web = clientContext.Web;
            List list = web.Lists.GetByTitle(listName);

            string FolderFullPath = siteUrl + "contact/" + folderName;

            CamlQuery query = new CamlQuery();
            query.ViewXml = "<View Scope=\"RecursiveAll\"> " +
                            "<Query>" +
                                "<Where>" +
                                    "<And>" +
                                        "<Eq>" +
                                            "<FieldRef Name=\"FSObjType\" />" +
                                            "<Value Type=\"Integer\">1</Value>" +
                                         "</Eq>" +
                                          "<Eq>" +
                                            "<FieldRef Name=\"Title\"/>" +
                                            "<Value Type=\"Text\">" + folderName + "</Value>" +
                                          "</Eq>" +
                                    "</And>" +
                                 "</Where>" +
                            "</Query>" +
                            "</View>";

            if (relativePath.Equals(string.Empty))
            {
                query.FolderServerRelativeUrl = "/lists/" + listName;
            }
            else
            {
                query.FolderServerRelativeUrl = "/lists/" + listName + "/" + relativePath;
            }
            var folders = list.GetItems(query);

            clientContext.Load(list);
            clientContext.Load(list.Fields);
            clientContext.Load(folders, fs => fs.Include(fi => fi["Title"],
                fi => fi["DisplayName"],
                fi => fi["FileLeafRef"]));
            clientContext.ExecuteQuery();

但是我一直收到错误消息：“值未在预期范围内”。

这是日志：

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Value does not fall within the expected range.Detail:

由于您使用的是SharePoint CSOM API，因此我建议使用Web.GetFolderByServerRelativeUrl方法 来获取位于指定服务器相对URL上的文件夹对象。

例

var folderUrl = "Lists/Discussions/2013"; //folder named 2013 located in Discussions list
using (var ctx = new ClientContext(webUri))
{
   var folder = ctx.Web.GetFolderByServerRelativeUrl(folderUrl);
   ctx.Load(folder);
   ctx.ExecuteQuery();
}

如何使用SharePoint 2010 CSOM API重命名文件夹

下面的示例演示如何重命名文件夹：

public static class FolderExtensions
{
    public static void RenameFolder(this Folder folder,string name)
    {
        var folderItem = folder.ListItemAllFields;
        folderItem["Title"] = name;
        folderItem["FileLeafRef"] = name;
        folderItem.Update();
    }

}

用法

var folder = ctx.Web.GetFolderByServerRelativeUrl(folderUrl);
folder.RenameFolder("Archive");  //<-set new folder name here
ctx.ExecuteQuery();
