How to Efficiently Convert an Integer to its Binary Representation in C#?

Conversion of integer to binary representation in C#

Converting an integer to its binary representation is a common programming task. In C#, there are several ways to perform this conversion, including using the ToInt32 and ToString methods of the Convert class.

To demonstrate this process, let's solve a problem encountered by a user who was trying to convert an integer represented as a string into its binary representation:

<code>String input = "8";
String output = Convert.ToInt32(input, 2).ToString();</code>

This code throws an exception with the message "No parsable numbers found". This is because ToInt32 expects the input string to represent a decimal integer, not a binary integer, and the string "8" represents the decimal value 8.

To correctly convert an integer to its binary representation, we use the Convert.ToString method and specify a base of 2. Here is an updated code snippet:

<code>int value = 8;
string binary = Convert.ToString(value, 2);</code>

This code converts an integer value (whose decimal value is 8) into a string representing its binary representation, resulting in the string "1000".
