title: Concat string inside an object?
body: <p>I was wondering what is the clean way to concat a string inside an object?</p>
  
  <pre><code>public class Example
  {
      public string name { get; set; }
  
  }
  
  public void BuildExample()
  {
     Example x = new Example();
     x.name = "Hello";
  
     sb = new StringBuilder();
     sb.Append(" children: [{");
  
     var parent = JsonConvert.SerializeObject(x);
     var output = string.Concat(parent.ToString(), sb);
  
   }
  </code></pre>
  
  <p>output</p>
  
  <pre><code>{"name":"Hello"} children: [{
  </code></pre>
  
  <p>desired output</p>
  
  <pre><code>{
   "name":"hello",
    children: [{
  </code></pre>
