C# Implementation method of using reflection to determine whether an object contains a certain attribute

This article shows the implementation method of C# using reflection to determine whether an object contains a certain attribute, which has certain learning value for C# programmers.

The specific implementation code is as follows:

/// &lt;summary&gt;
/// Use reflection to determine whether an object contains a certain attribute/// &lt;/summary&gt;
/// &lt;param name="instance"&gt;object&lt;/param&gt;
/// <param name="propertyName">Properties that need to be judged</param>/// <returns> Whether to include</returns>public static bool ContainProperty(this object instance, string propertyName)
{
  if (instance != null &amp;&amp; !(propertyName))
  {
 PropertyInfo _findedPropertyInfo = ().GetProperty(propertyName);
 return (_findedPropertyInfo != null);
  }
  return false;
}

The code usage method is as follows:

bool cc = _person.ContainProperty("cc");
bool aa = _person.ContainProperty("Age");

I hope the examples described in this article can be helpful to everyone!
