推荐答案

希望 ASP.NET树视图-具有自定义的树节点 [

Hope ASP.NET Tree View - with customized tree nodes[^]this article from CP might help you.

在这里您可以找到文件夹的整体大小.

Here is how you can find the whole size of the folder.

DirectoryInfo dirInfo=new DirectoryInfo(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments));

double fileSize=0;
foreach(FileInfo fi in dirInfo.GetFiles("*.*",SearchOption.AllDirectories))
{
//fileSize will have the total size displayed in bytes
fileSize+=fi.Length;
}

在将文件夹加载到树形视图中时尝试获取文件夹大小(我在这里假设您将使用根目录结构来构建此TreeView某处).

Try to get the folder size when you are loading the folder into the treeview (I am assuming here that you would be building this TreeView using the root directory structure somewhere).
