Obtains information about a folder and generates an XML file, which is displayed in the tree.

Because the company wants to prepare a software for online upgrading of servers and clients, it needs to obtain the file path information on the server and generate the corresponding XML file for a small software test, we have done it today ~~

Useful friends can learn from, mainlyCodeAs follows:

 

Private Xmldocument xmldoc;

Private   Void Btncreatexml_click ( Object Sender, eventargs E)
{
// Custom file path
String Strpath =   " F: \ work2 \ bkjj \\ " ;

Xmldoc =   New Xmldocument ();
Xmldoc. loadxml ( " <Directory> </directory> " );

Try
{
Directoryinfo d1 =   New Directoryinfo (strpath );
Filesysteminfo [] FSI = D1.getfilesysteminfos ();

Foreach (Filesysteminfo FS In FSI)
{
Xmlnode XN = Xmldoc. selectsinglenode ( " Directory " );
If (FS Is Directoryinfo)
{

Xmlelement XE = Xmldoc. createelement ( " Directory " );
Xmlattribute xA1 = Xmldoc. createattribute ( " Path " );
Xmlattribute xa2 = Xmldoc. createattribute ( " Size " );
Xa1.value = FS. fullname;
Xa2.value = Getdirectsize (FS. fullname). tostring ();
Xe. Attributes. append (xA1 );
Xe. Attributes. append (xa2 );
XN. appendchild (xe );
// Loop traversal,Transferring the current node is the key, because it has been around for a long time.
Loopdirectory (FS. fullname, Xe );
}
Else
{
Fileinfo F1 =   New Fileinfo (FS. fullname );

Xmlelement XE = Xmldoc. createelement ( " File " );
Xmlattribute xA1 = Xmldoc. createattribute ( " Path " );
Xmlattribute xa2 = Xmldoc. createattribute ( " Size " );
Xa1.value = FS. fullname;
Xa2.value = F1.length. tostring ();
Xe. Attributes. append (xA1 );
Xe. Attributes. append (xa2 );

XN. appendchild (xe );

}
}
}
Catch (Exception ex)
{
MessageBox. Show (ex. Message );
}
Finally
{
Xmldoc. Save ("Fileinfo. xml");
}
}

// Traverse the folder in the given path and create a node in the current xmlelement
Private   Void Loopdirectory ( String Strpath, xmlelement Ele)
{
Directoryinfo d1 =   New Directoryinfo (strpath );
Filesysteminfo [] FSI = D1.getfilesysteminfos ();
Foreach (Filesysteminfo FS In FSI)

Xe. Attributes. append (xA1 );
Xe. Attributes. append (xa2 );

Ele. appendchild (xe );
}
}
}

// Obtains the size of a folder. Here, we use other people's code.
Private   Long Getdirectsize ( String Filepath)
{

{
