C# BitConverter.ToUInt32() Method


The BitConverter.ToUInt32() method in C# is used to return a 32-bit unsigned integer converted from four bytes at a specified position in a byte array.

Syntax

public static uint ToUInt32 (byte[] val, int begnIndex);

Above, val is the byte array, whereas begnIndex is the starting position withing val.

Example

 Live Demo

using System;
public class Demo {
   public static void Main() {
      byte[] arr = { 0, 3, 5, 10, 15, 2};
      int count = arr.Length;
      Console.Write("Byte Array... ");
      for (int i = 0; i < count; i++) {
         Console.Write("\n"+arr[i]);
      }
      Console.WriteLine("\n\nByte Array (String representation) = {0} ",
      BitConverter.ToString(arr));
      for (int i = 1; i < arr.Length - 1; i = i + 4) {
         uint res = BitConverter.ToUInt32(arr, i);
         Console.WriteLine("\nValue = "+arr[i]);
         Console.WriteLine("Result = "+res);
      }
   }
}

Output

Byte Array...
0
3
5
10
15
2
Byte Array (String representation) = 00-03-05-0A-0F-02
Value = 3
Result = 252314883

Example

 Live Demo

using System;
public class Demo {
   public static void Main() {
      byte[] arr = { 0, 0, 1, 3, 5, 7, 9, 11, 15 };
      int count = arr.Length;
      Console.Write("Byte Array... ");
      for (int i = 0; i < count; i++) {
         Console.Write("\n"+arr[i]);
      }
      Console.WriteLine("\n\nByte Array (String representation) = {0} ",
      BitConverter.ToString(arr));
      for (int i = 1; i < arr.Length - 1; i = i + 4) {
         uint res = BitConverter.ToUInt32(arr, i);
         Console.WriteLine("\nValue = "+arr[i]);
         Console.WriteLine("Result = "+res);
      }
   }
}

Output

Byte Array...

Byte Array (String representation) = 00-00-01-03-05-07-09-0B-0F
Value = 0
Result = 84082944
Value = 7
