String Reversal using a loop

Could I please get an example of how to reverse a string such as abcde using a loop?

Thanks

public string Reverse_String(string strToReverse)
{
string strToReturn="";
for (int i=strToReverse.Length; i>=0; i--)
{
strToReturn += strToReverse[i];
}
return strToReturn;
}

EDIT:

just realized you probably wanted VB

Function Reverse_String(strToReverse as String) as String
dim strToReturn as string = ""
dim i as integer;
For i=strToReverse.Length To i=0 Step -1
strToReturn = strToReturn & strToReverse(i)
Next i
End Function
