• This is odd.  What are you using to Reverse the words in your sentence?  Can you not split your sentence on the spaces and reconstruct it in reverse?  Something like this:

private string ReverseString(string str)
{
string[] Revstr;
Revstr = Regex.Split(str.ToString(), " ");
int r = Revstr.Length;
str = "";
for(int i=r-1;i>=0;i--)
{
str = str + " " + Revstr[i];
}
return str;
}

• Do you want the reversal only to occur for apha numeric strings?

In that case, Andrew's function could be modified to:-
```private string ReverseString(string str)
{
if (Regex.IsMatch(str,"[1-9]"))
{
string[] Revstr;
Revstr = Regex.Split(str.ToString(), " ");
int r = Revstr.Length;
str = "";
for(int i=r-1;i>=0;i--)
{
str = str + " " + Revstr[i];
}

}
return str;
}```

• Many thanks for you.
But I can not do this that is because i retrive this field from DB and i don't sure that this string always be Alphanumeric
like :
if this string is "soma 3slia" after reverse it will be "3slia soma".
