How Do I Correctly Convert a VB.NET Object's String Property to a C# Byte Array?

Convert string to byte array in C#

You may encounter syntax issues when trying to convert a string to a byte array in C#. Let's explore a specific case and its solution.

Question:

Trying to convert a VB object's property value to a C# byte array results in the error:

<code>Argument 1: cannot convert from 'object' to 'byte[]'</code>

Solution:

To successfully convert an attribute value, you need to know the encoding used in the original conversion. For example:

<code class="language-csharp">byte[] bytes = System.Text.Encoding.ASCII.GetBytes(originalString);
string encodedString = System.Text.Encoding.ASCII.GetString(bytes);</code>

If you don't know the encoding used, you can examine the inherited code for clues. System.Text.Encoding class provides various encodings including ASCII, UTF8, Unicode and UTF32. See the documentation for a complete list.

Please note that the code you provided:

<code class="language-csharp">string User = Encoding.UTF8.GetString("user", 0);</code>

is wrong because it tries to convert a string to a byte array without any actual data to convert. In the provided VB statement, searchResult.Properties["user"][0] is an object containing a byte array, which needs to be accessed and converted appropriately.
