I am confused how Convert.ToInt32() works?

fixed the issue. Will look into that further Convert.ToInt32() takes a string that only contains numeric characters. Anything else is an error. Converting english-language words (such as "five") into a numeric value isn't what Convert.ToInt32() does.
If you want to convert strings such as "one hundred and fifteen" into an int, it's a little more complicated. Here's an answer I wrote for fun a while ago that does just this (albeit to long rather than int):

What is the major differences between Convert.ChangeType or Convert.ToInt32?

This might help you If you know you're going to be converting a string to Int32, using Convert.ChangeType seems an obscure way of doing that. I would definitely prefer either of the other calls to that.
The main difference between int.Parse and Convert.ToInt32(x) is that Convert.ToInt32(null) returns 0 where as int.Parse(null) will throw an exception. Of course, int.Parse also gives you more control in terms of what culture is used.

Convert.ToInt32 in C#

I wish this help you Your code works, but you have set your debugger to display integers in hexadecimal. The value 0x0001d524 is the hexadecimal representation of the integer 120100.
This is not an error in the program, but a configuration option for your IDE. If you use Visual Studio, you can change this setting by pressing the "Hex" button in the "Debug" toolbar.
maxJobOrder = result.Max(x => int.Parse(x.JobOrder));

it should still fix some issue You can't convert a byte[] to an int using Convert.ToInt32. You need to use a BitConverter.
The difference is that the BitConverter is built to do exactly what you're trying to do: take an array of bytes and convert them into their integral representation. Convert.Int32 is meant for converting anything that's already an integer, or can be converted to an integer using the IConvertible interface.

is ToInt32() an extension method in C#? specially Convert.ToInt32()

Tag : chash , By : fayoh

seems to work fine No. An extension method's raison d'être is to allow the instance method invocation syntax to be used for methods declared outside the type. You'll find that you cannot do that with any of the Convert.ToInt32 methods.
For example, the type String does not have a ToInt32(String) member method. If you wanted to convert a String to an Int32, you could write a static method like this:
public static class StringConverters
    public static Int32 ToInt32(String number)
        return Int32.Parse(
var n = StringConverters.ToInt32("12345");
using static StringConverters; 
var n = ToInt32("12345");
public static class StringConverters 
    public static Int32 ToInt32(this String number)
        return Int32.Parse(
var n = "12345".ToInt32();
