string--> charArray--->Count()
protected void Button1_Click(object sender, EventArgs e)
       {
           string text = TextBox1.Text;
           char[] textToCharArray = text.ToCharArray();
           int noOfZeros = textToCharArray.Where(x => x == '0').Count();
           int noOfOnes = textToCharArray.Where(x => x == '1').Count();
       }

Hello Preetham, can you check this sample.
string str = "1011110000Ah";
char [] lst = str.ToCharArray(); // your TextboxName.Text.ToCharArray();
int Ones= lst.Count(k => k == '1');
int Zeros= lst.Count(k => k == '0');

Hello,
Good Morning.

If I assume that the user enters only numeric values in the text box then below is the logic to achieve the solution of above problem definition.
string userEnteredData = "10102310120011110";

if(!string.IsNullOrWhiteSpace(userEnteredData))
{
List<int> arr = userEnteredData.ToCharArray().Select(x => Convert.ToInt32( x.ToString())).ToList();
int CountOfOne = arr.Where(x => x == 1).Count();
int CountOfZero = arr.Where(x => x == 0).Count();
}
