Question

What would be the best way to determine if an object equals number zero (0) or string.empty in C#?

EDIT: The object can equal any built-in System.Value type or reference type.

Source Code:

public void MyMethod(object input1, object input2) {     bool result = false;     object compare = new object();      if(input != null && input2 != null)     {         if(input1 is IComparable && input2 is IComparable)         {             //do check for zero or string.empty             //if input1 equals to zero or string.empty             result = object.Equals(input2);              //if input1 not equals to zero or string.empty             result = object.Equals(input1) && object.Equals(input2); //yes not valid, but this is what I want to accomplish         }     } }

Using Jonathan Holland code sample with a minor modification, here is the solution that worked:

static bool IsZeroOrEmpty(object o1) {     bool Passed = false;     object ZeroValue = 0;      if(o1 != null)     {         if(o1.GetType().IsValueType)         {             Passed = (o1 as System.ValueType).Equals(Convert.ChangeType(ZeroValue, o1.GetType()))         }         else         {             if (o1.GetType() == typeof(String))             {                 Passed = o1.Equals(String.Empty);             }         }     }      return Passed; }
