How to convert an int32 to a string

In C#, converting an int (Int32) to a string is very simple.

Here are the most common and recommended methods:

1. Using .ToString() (Most common & cleanest)

int number = 123;
string result = number.ToString();

2. Using string interpolation

int number = 123;
string result = $"{number}";

3. Using Convert.ToString()

int number = 123;
string result = Convert.ToString(number);

For formatting:

Add leading zeros

int number = 7;
string result = number.ToString("D4");  // output: "0007"

Format with commas

int number = 1000000;
string result = number.ToString("N0");  // output: "1,000,000"

Quick summary:

If you want the reverse (string ? int), I can also show you the safest way using int.TryParse().

int myNum= 2005; 
string myString= myNum.ToString(); 
Console.WriteLine(myString);

Output:
"2005"

use the most cleanest and direct method to convert an int (or Int32) to a string in C#.

int number = 123;

string text = number.ToString();

You can convert an int to a string using the built-in .ToString() method — the simplest and most common approach.

Example:

int number = 12345;
string text = number.ToString();

Console.WriteLine(text); // Output: "12345"

If you want a formatted string (e.g., with commas):

int number = 10000;
string formatted = number.ToString("N0"); 

Console.WriteLine(formatted); // Output: "10,000"

int number = 123;
string text = number.ToString();

int32 to string conversion depends on programming language which is used. Following are some common examples:

C#

int number = 12345;

string str = number.ToString();

C++

#include 

int number = 12345;

std::string str = std::to_string(number);

 int number = 123; 
string  str = number.ToString();
string str1 = Convert.ToString(number);

int x = 42;

string s = x.ToString(); // Converts to string

Console.WriteLine(s); // "42"

There are multiple suggestions to use the Int32.ToString method without a parameter but if you look at the documentation you will see that it is possible to format numbers using a parameter or two.

Also, the following:

  
    Console.WriteLine($"{s}");
  

Is equivalent to:

  
string s = num.ToString();
Console.WriteLine(s);
