Overriding Equals method in Structs

Question

I\'ve looked for overriding guidelines for structs, but all I can find is for classes.

At first I thought I wouldn\'t have to check to see if the passed object was n

Answer 1

Thanks to pattern matching in C# 7.0 there is an easier way to accomplish the accepted answer:

struct MyStruct 
{
    public override bool Equals(object obj) 
    {
        if (!(obj is MyStruct mys)) // type pattern here
            return false;

        return this.field1 == mys.field1 && this.field2 == mys.field2 // mys is already known here without explicit casting
    }
}

You could also make it even shorter as an expression-bodied function:

struct MyStruct 
{
    public override bool Equals(object obj) => 
        obj is MyStruct mys
            && mys.field1 == this.field1
            && mys.field2 == this.field2;
}
