You will have to convert it explicitly to an array and then loop the array.
I think at the moment the foreach loop goes throug once.

string[] arr = x.Split("\");
foreach string s in arr
{
this.txtdepartment.text += s + " ";
}

cheers

I would recomend a regular for loop, as this will give you control over keeping the last word.

string[] arr = x.Split("\");
//use < Length-1 to ensure you ignore the last word
for (int i=0; i<arr.Length-1;i++)
{
 string temp=arr[i];
 //do whatever you want with temp
}
 

or in vb.net:

Dim arr As String() = x.Split("\".ToCharArray()) 
'use < Length-1 to ensure you ignore the last word 
For i As Integer = 0 To (arr.Length - 1) - 1 
    Dim temp As String = arr(i) 
    'do whatever you want with temp 
Next

Hi,
could you please put in what you are doing with the code sent above.

The code given by Plater is 100% to what you should need.
Its what you are doing with it matters.

cheers

I will try again as a bit of pseudo code

string mys= "cafe\restaurant\hotel";
//and then you Split() it
string[] pieces = mys.Split(@"\".ToCharArray());
//then pieces will now look like this:
//pieces[0]="cafe";
//pieces[1]="restaurant";
//pieces[2]="hotel";
 
//Now you need to loop from index 0 to index 1 
//since pieces.Length=3,  and you only want index's 0,1
//you would use < pieces.Length-1 
for (int i=0;i<pieces.Length-1,i++)
{
  string temp=pieces[i];
  //now temp will = "cafe" when i=0 and "restaurant" when i=2
  //if I have to explain more loop logic to you, you really need to go 
  //back and read some tutorials on "the basics"
}
