严重的逻辑错误
本文关键字:错误 | 更新日期: 2023-09-27 18:19:30
我正在尝试下载网站的所有子网站中的所有文档库,下面给出了代码,但由于某些原因,它没有创建正确的目录结构,当我尝试调试时,在代码之后,我得到了一个异常,如下所示。
private void bFolder_Click(object sender, EventArgs e)
{
TreeNode currentNode = tvSource.SelectedNode;
SPObjectData objectData = (SPObjectData)currentNode.Tag;
using (SPWeb TopLevelWeb = objectData.Web)
{
string CurrentPath = tbDirectory.Text;
string FolderName = TopLevelWeb.Name;
dwnEachWeb(TopLevelWeb, CurrentPath, FolderName);
}
}
private void dwnEachWeb(SPWeb TopLevelWeb, string CurrentPath, string FolderName)
{
if (TopLevelWeb != null)
{
if (TopLevelWeb.Webs != null)
{
CreateDirectoryStructure(CurrentPath, FolderName);
dwnEachList(TopLevelWeb, CurrentPath, FolderName);
foreach (SPWeb ChildWeb in TopLevelWeb.Webs)
{
FolderName = ChildWeb.Name;
CurrentPath = CurrentPath + "''" + FolderName;
dwnEachWeb(ChildWeb, CurrentPath, FolderName);
ChildWeb.Dispose();
}
}
}
}
private void dwnEachList(SPWeb oWeb, string CurrentPath, string FolderName)

{
if (oList is SPDocumentLibrary && !oList.Hidden)
{

FolderName = oList.Title;
CreateDirectoryStructure(CurrentPath, FolderName);
dwnEachFile(oList.RootFolder, CurrentPath, FolderName);
}
}
}

正在尝试在OS Loader锁内进行托管执行。不要尝试在DllMain或映像初始化函数内运行托管代码,因为这样做可能会导致应用程序挂起。
错误出现在"dwnEachWeb(ChildWeb,CurrentPath,FolderName);"行
但我很确定我的逻辑是不对的,也许
