Solution 1

If the data type od Result is string:

Use the int32 TryParse method[^] or the float TryParse method to figure out the type of your value.

E.g. bool result = Int32.TryParse(Result, out number);

So you can use

if (Int32.TryParse(Result, out number))
{
  //Then value is integer 
}

int Ratings = Convert.ToInt32(ds.Tables[0].Rows[0]["StarCount"].ToString());
int People = Convert.ToInt32(ds.Tables[0].Rows[0]["PeopleCount"].ToString());
float f1 = (float)Ratings;

float r1 = f1 / People;
Result = Convert.ToString(r1);
// Result = Result.Substring(0, 3);

// double result = (double)r1;
//float Toatl = Ratings / People;
Result = Result.ToString();
//Result = Int32.TryParse(Result, out number);
if (Int32.TryParse(Result, out number))
{
//Then value is integer
}
Result = Result.Substring(0, 3);
TotalPPl = People.ToString();

is the code used for rating so here Result=Result.Substring(0,3)
i want to include inside if condition where if Result is 10 it should not
go to Result=Result.Substring(0, 3);

so, i used above condition but out number showing error so can u please tell how to include if condition in above code...

thanks in advance!

Define number before using it in TryParse:

int32 number = 0;
if (Int32.TryParse(Result, out number))
{
//Then value is integer
}

It works great on strings. Just to make it clear to OP or to some beginner who shall stumble upon this in future, you should provide write Result.ToString().
5.
