C # uses reflection to determine whether an object contains an implementation of an attribute

This example shows that C # uses reflection to determine whether an object contains an attribute, and for C # program designers, it has a certain learning value.

The specific implementation code is as follows:

<SUMMARY>///uses reflection to determine whether an object contains an attribute//</summary>///<param name= "instance" >object</param>// /<param name= "PropertyName" > Properties to be judged </param>///<returns> contains </returns>public static bool Containproperty (This object instance, string propertyname) {  if (instance! = null &&!string. IsNullOrEmpty (PropertyName))  {PropertyInfo _findedpropertyinfo = instance. GetType (). GetProperty (PropertyName); Return (_findedpropertyinfo! = null);  }  return false;}

Here's how to use the code:

bool cc = _person. Containproperty ("CC"); bool AA = _person. Containproperty ("Age");

I hope that the examples described in this article can help you!
