Convert int to String in C#

To convert an int to a string in C#, you can use the ToString() method, which is available on all int variables. Here's an example:

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

To convert an int to a hexadecimal string, you can use the ToString() method with the "X" format specifier:

int number = 255; string hexString = number.ToString("X"); 

To convert an int to a fixed-length hexadecimal string with leading zeros, you can use the ToString() method with the "X" format specifier and a minimum width:

int number = 255; string hexString = number.ToString("X2"); // output: "FF" 

To convert an int to a binary string, you can use the Convert.ToString() method with a 2 as the second argument:

int number = 5; string binaryString = Convert.ToString(number, 2); // output: "101" 

To convert an int to an ASCII string, you can cast it to a char:

int number = 65; string asciiString = ((char)number).ToString(); // output: "A" 

Note that this only works for int values that represent valid ASCII characters (i.e. between 0 and 127).

Examples

1. C# convert int to string example:

   int number = 42; string resultString = number.ToString(); // Result: "42" 

2. ToString() method for int to string in C#:

   int number = 42; string resultString = number.ToString(); // Result: "42" 

3. C# int to string conversion:

   int number = 42; string resultString = Convert.ToString(number); // Result: "42" 

4. String.Format C# int to string:

   int number = 42; string resultString = string.Format("{0}", number); // Result: "42" 

5. C# convert int to string with leading zeros:

   int number = 42; string resultString = number.ToString("D4"); // D4 means use at least 4 digits with leading zeros // Result: "0042" 

6. Casting int to string in C#:

   int number = 42; string resultString = ((long)number).ToString(); // Explicit casting to long // Result: "42" 

7. String interpolation for int to string C#:

   int number = 42; string resultString = $"{number}"; // Result: "42" 

8. Convert.ToString() C# int to string:

   int number = 42; string resultString = Convert.ToString(number); // Result: "42" 

9. Concatenate int with string in C#:

   int number = 42; string prefix = "The number is "; string resultString = prefix + number; // Result: "The number is 42" 

10. C# int to hexadecimal string conversion:

    int number = 42; string hexString = number.ToString("X"); // X means hexadecimal // Result: "2A"
