我想下载多个文件,例如使用正则表达式,其中用户通过变量提供文件名,并在caml查询中传递该文件名,并且可以循环访问列表URL。这个caml查询区域有点新。有什么建议可以实现吗?
camlQuery.ViewXml = @"<View>
<Query>
<Where><Eq><FieldRef Name='FileLeafRef' /><Value Type='File'>" + fileToDownload + @"</Value></Eq></Where>
</Query>
<ViewFields><FieldRef Name='FileRef' /><FieldRef Name='FileLeafRef' /></ViewFields>
</View>";
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.Load(web.Lists);
List list = clientContext.Web.GetList(listUrl);
//clientContext.Load(list);
//clientContext.ExecuteQuery();
ListItemCollection listItems = list.GetItems(camlQuery);
clientContext.Load(listItems);
clientContext.ExecuteQuery();
foreach (var item in listItems)
{
if (item.FileSystemObjectType == FileSystemObjectType.File)
{
Console.WriteLine("This is file");
}
else if (item.FileSystemObjectType == FileSystemObjectType.Folder)
{
Console.WriteLine("This is folder");
}
camlQuery.ViewXml = @"<View>
<Query>
<Where><Eq><FieldRef Name='FileLeafRef' /><Value Type='File'>" + fileToDownload + @"</Value></Eq></Where>
</Query>
<ViewFields><FieldRef Name='FileRef' /><FieldRef Name='FileLeafRef' /></ViewFields>
</View>";
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.Load(web.Lists);
List list = clientContext.Web.GetList(listUrl);
//clientContext.Load(list);
//clientContext.ExecuteQuery();
ListItemCollection listItems = list.GetItems(camlQuery);
clientContext.Load(listItems);
clientContext.ExecuteQuery();
foreach (var item in listItems)
{
if (item.FileSystemObjectType == FileSystemObjectType.File)
{
Console.WriteLine("This is file");
}
else if (item.FileSystemObjectType == FileSystemObjectType.Folder)
{
Console.WriteLine("This is folder");
}
我需要从FiletoDownload变量上的匹配模式下载文件,就像它的。一样。它应该下载所有文件。
