string remove char possibly a catastrophic wreck.

[aronmatthew]

string= string.Remove(string.IndexOf('.'),1);

The first parameter is supposed to be the start index, not the character to be removed. The compiler is getting the ASCII value of character '.' and passing that in.

Please see the documentation:

String.Remove Method (System)

Returns a new string in which a specified number of characters from the current string are deleted.

What about when using index of..it throws index exception in that case. There must be a way using just remove method. Unfortunately I'm too busy and this very frustrating problem is like getting pulled over by crooked cops.

This is absolutely ridiculous like getting pulled over by police.

What's wrong with IndexOf()? This seems to work just fine:

Code:

using System;
                   
public class Program
{
    public static void Main()
    {
        var temp1 = "6.";
       
        var indexOfDot = temp1.IndexOf('.');
        if (indexOfDot >= 0)
            temp1 = temp1.Remove(indexOfDot);

        Console.WriteLine(temp1);
    }
}

Output:

6

But I think what you really want is something like this:

using System;
                    
public class Program
{
    public static void Main()
    {
        var temp1 = "6.";
        int value = 0;
        
        if (double.TryParse(temp1, out var doubleValue))
        {
            value = (int)doubleValue;
        }
        else
        {
            throw new FormatException($"Could not parse {temp1}");
        }
        Console.WriteLine(value);
    }
}

Or you could just do:

temp1 = temp1.Replace(".", "");

Is the dot always going to be at the end if it's present? If so, just use TrimEnd.
