Anonymous type equality C# with Example



Anonymous type equality C# with Example

Anonymous type equality is given by the Equals instance method. Two objects are equal if they have the same type 
and equal values (through a.Prop.Equals(b.Prop)) for every property. 
var anon = new { Foo = 1, Bar = 2 }; 
var anon2 = new { Foo = 1, Bar = 2 }; 
var anon3 = new { Foo = 5, Bar = 10 }; 
var anon3 = new { Foo = 5, Bar = 10 }; 
var anon4 = new { Bar = 2, Foo = 1 }; 
// anon.Equals(anon2) == true 
// anon.Equals(anon3) == false 
 

// anon.Equals(anon4) == false (anon and anon4 have different types, see below) 
Two anonymous types are considered the same if and only if their properties have the same name and type and 
appear in the same order. 
var anon = new { Foo = 1, Bar = 2 }; 
var anon2 = new { Foo = 7, Bar = 1 }; 
var anon3 = new { Bar = 1, Foo = 3 }; 
var anon4 = new { Fa = 1, Bar = 2 }; 
// anon and anon2 have the same type 
// anon and anon3 have diferent types (Bar and Foo appear in different orders) 
// anon and anon4 have different types (property names are different)
