我创建了一个应用程序,该应用程序下载了SP网站中的所有文档库,但有一次它给了我这个错误(我尝试查看Google,但找不到任何东西,现在,如果有人知道解决此问题的任何技巧,请回复,否则,谢谢看看)
System.IO.PathTooLongException:指定的路径,文件名或两者都太长。完全限定的文件名必须少于260个字符,目录名称必须少于248个字符。在System.IO.Path.NormalizePathFast(字符串路径,布尔fullCheck)在System.IO.Path.GetFullPathInternal(字符串路径)在System.IO.FileStream.Init(字符串路径,FileMode模式,FileAccess访问,Int32权限,布尔useRights ,FileShare共享,Int32 bufferSize,FileOptions选项,SECURITY_ATTRIBUTES secAttrs,System.IO.FileStream..ctor(字符串路径,FileMode模式,FileAccess访问,FileShare共享,Int32 bufferSize,FileOptions选项)位于System.IO.FileStream..ctor。 IO.File.Create(字符串路径)
它达到了字符串的限制,代码如下所示,
#region Downloading Schemes
private void btnDownload_Click(object sender, EventArgs e)
{
TreeNode currentNode = tvWebs.SelectedNode;
SPObjectData objectData = (SPObjectData)currentNode.Tag;
try
{
CreateLoggingFile();
using (SPWeb TopLevelWeb = objectData.Web)
{
if(TopLevelWeb != null)
dwnEachWeb(TopLevelWeb, TopLevelWeb.Title, tbDirectory.Text);
}
}
catch (Exception ex)
{
Trace.WriteLine(string.Format("Exception caught when tried to pass TopLevelWeb:{1}, Title = {2}, object data to (dwnEachWeb_method), Exception: {0}", ex.ToString(), objectData.Web, objectData.Title));
}
finally
{
CloseLoggingFile();
}
}
private void dwnEachWeb(SPWeb TopLevelWeb, string FolderName, string CurrentDirectory)
{
if (TopLevelWeb != null)
{
if (TopLevelWeb.Webs != null)
{
CurrentDirectory = CurrentDirectory + "\\" + TopLevelWeb.Title;
CreateFolder(CurrentDirectory);
foreach (SPWeb ChildWeb in TopLevelWeb.Webs)
{
}
}
}
