    copied!<p>I'm not looking for a comparison of two structs that returns bool, I am wondering if there is a way to get which fields of two structs (the same structure, but maybe different values) are different. Basically I want a simpler way to do the following:</p> <pre><code>public class Diff { public String VarName; public object Val1; public object Val2; public Diff(String varName, object val1, object val2) { VarName = varName; Val1 = val1; Val2 = val2; } public override string ToString() { return VarName + " differs with values " + Val1 + " and " + Val2; } } public struct TestStruct { public int ValueOne; public int ValueTwo; public int ValueThree; public List Compare(TestStruct inTestStruct) { List diffs = new List(); if (ValueOne != inTestStruct.ValueOne) { diffs.Add(new Diff("ValueOne", ValueOne, inTestStruct.ValueOne)); } if (ValueTwo != inTestStruct.ValueTwo) { diffs.Add(new Diff("ValueTwo", ValueTwo, inTestStruct.ValueTwo)); } if (ValueThree != inTestStruct.ValueThree) { diffs.Add(new Diff("ValueThree", ValueThree, inTestStruct.ValueThree)); } return diffs; } } public CompareStructsExample() { TestStruct t1 = new TestStruct(); t1.ValueOne = 1; t1.ValueTwo = 8; t1.ValueThree = 5; TestStruct t2 = new TestStruct(); t2.ValueOne = 3; t2.ValueTwo = 8; t2.ValueThree = 7; List diffs = t1.Compare(t2); foreach (Diff d in diffs) { System.Console.WriteLine(d.ToString()); } } </code></pre> <p>I'm wondering if there is a way to do this with serialization of some sort, or if this is the only way to actually see which values have changed. Even if there is a better way to implement the Compare function, I would take that too.</p>
