How to Ensure Consistent Byte Representations of Strings in C#?

The bytes of the string of the string indicate the consistency

When processing the string in C#, it is important to understand the importance of byte representation and character coding. One problem that developers often encounter are how to convert the string into byte array when the coding is not explicitly specified. This is especially important when encrypted string.

byte representation and character coding

character coding specifies how to use byte sequence to represent the string. Different codes, such as ASCII, UTF-8, and UTF-16, define how each character corresponds to a byte value. When switching data between different systems or stored data in a manner that can be accurately explained later, coding is essential.

Convert the string to byte array

To convert the string to byte array without specified coding, you can use the getbytes () method:

This method returns a byte array that uses its default character code to represent the string, which usually depends on the system and runtime environment and is UTF-8 or UTF-16.

In some cases, the cause of unrelated coding

<code class="language-csharp">byte[] bytes = str.GetBytes();</code>

In contrast, you don't always need to pay attention to character coding. If your goal is only the bytes of the storage and retrieval of the string without explaining it as a text, you can avoid the complexity of the coding. For this:

This method stores the original bytes of the string. As long as you don't try to interpret the byte as text, you don't need to worry about coding. This can simplify your code and eliminate potential complications caused by invalid characters.
