title: What do dollar symbols in C# Code mean?
body: <p>Today, I pull the code from my client, and I get an error in this line.</p>
  
  <pre><code>throw new Exception($"One or more errors occurred during removal of the company:{Environment.NewLine}{Environment.NewLine}{exc.Message}");
  </code></pre>
  
  <p>This line also</p>
  
  <pre><code>moreCompanies = $"{moreCompanies},{databaseName}";
  </code></pre>
  
  <p>The $ symbols is so weird with me. This is C# code.</p>
