Use a loop and check for each cell data with the special characters that you want to check and perform your operation that you wanted to do.

I'm not sure what you mean by 'special characters' but if you want to trap control characters you can do something like this.

C#

string MyString = "FirstLine\r\nSecondLine\t tabbed";
             if (MyString.Any(c => char.IsControl(c)))
            {
                Console.WriteLine("Found Control character");
            }

Solution 1

foreach (DataRow row in dt.Rows)
{
for (int i = 0; i < dt.Columns.Count; i++)
{
if(dt.Columns[i].DataType == typeof(string))
row[i] = ReplaceHexadecimalSymbols((string)row[i]);
}
}

my bad, i over looked it

C#

static string ReplaceHexadecimalSymbols(string txt)
{
string r = "[\x00-\x08\x0B\x0C\x0E-\x1F\x26]";
return Regex.Replace(txt, r,"",RegexOptions.Compiled);
}

ReplaceHexadecimalSymbols? There's no inbuilt method to replace hexadecimal symbols. Did you forget to post this method?
