How to Convert Byte Arrays to Strings in C# Without Using BinaryReader?

No need for BinaryReader in C# to convert byte array to string

When manipulating data in a byte array, it is often necessary to convert it to a string for further processing or display. This article explores how to perform this conversion using C# without relying on the BinaryReader class.

Question:

You have created a byte array containing one or more strings and need to retrieve the string value from the byte array. However, due to compatibility restrictions, the BinaryReader class cannot be used.

Solution:

To convert a byte array to a string, you can use the System.Text.Encoding.Default.GetString() method. This method takes a byte array as input and automatically determines the appropriate encoding based on the system's default settings.

<code class="language-csharp">byte[] result = reader.ReadBytes((int)binWriter.BaseStream.Length);
var str = System.Text.Encoding.Default.GetString(result);</code>

However, it is important to note that the default encoding may not always suit your specific needs. In this case, you can explicitly specify the desired encoding using one of the following methods:

<code class="language-csharp">// 使用 ASCII 编码转换
var str = System.Text.Encoding.ASCII.GetString(result);

// 使用 UTF-8 编码转换
var str = System.Text.Encoding.UTF8.GetString(result);

//等等</code>
