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

Conversion from integer to binary in C#

When dealing with binary numbers, it is crucial to understand how to convert an integer to its binary representation. In C#, this conversion is very simple.

You provided a code example illustrating this issue:

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

However, this code throws an exception because you are trying to convert a string to an integer using base 2. To solve this problem, the string input must first be converted to an integer.

Correct conversion method

The correct way is to use the Convert.ToString method to directly convert the input integer to a binary string. Here's an example:

<code class="language-csharp">int value = 8;  // 请替换为您自己的整数
string binary = Convert.ToString(value, 2);</code>

This returns "1000", the binary representation of 8. Remember to use base 2 to specify that the output should be in binary format.
