c# - Type comparison not returning expected result -

i using following code compare types datacontractserializer re-initialize correct type if necessary.

    private void initializeserializer(type type)     {         if (this.serializer == null)         {             this.serializer = new datacontractserializer(type);             this.typetoserialize = type;         }         else         {             if (this.typetoserialize != null)             {                 if (this.typetoserialize.gettype() != type.gettype())                 {                     this.serializer = new datacontractserializer(type);                     this.typetoserialize = type;                 }             }         }     } 

for reason when compare 2 types result true , never enter final 'if' statement , re-initialize serialiser.

i can set break point @ comparison , see 2 types list<host> (this.typetoserialize.gettype()) , post (type.gettype())

both host , post share common ancestor shouldn't affecting result.

you calling gettype() on system.type. return system.type object describes system.type itself.

this makes code

if (this.typetoserialize.gettype() != type.gettype()) {    ... } 

equivalent to:

if(typeof(system.type) != typeof(system.type)) // false {    ... // never enters here } 

i'm guessing mean doing is:

if(typetoserialize != type) {    ... }
