title: What to use instead of string.Format with CultureInfo.InvariantCulture for just a single placeholder?
body: <p>I heard that there is no need to use string.Format with a single placeholder.</p>
  
  <p>For example, how can I change the following code accordingly, considering <code>CultureInfo.InvariantCulture</code>, </p>
  
  <pre><code>string myString = string.Format(CultureInfo.InvariantCulture, "{0}", myMethod());
  </code></pre>
  
  <p><code>myMethod()</code> returns a <code>string</code> object.</p>
  
  <p>Btw, I modified some existing code like the following  to have one place holder only</p>
  
  <pre><code>string myString = string.Format(CultureInfo.InvariantCulture, "{0}{1}", myMethod1(), myMethod2());
  </code></pre>
  
  <p>Thanks.</p>
