c# - Reference of object in array not kept -

i having problem reference object in list lost, how elaborated code :

propertyobject[] myproperties = new propertyobject[200]; var objparent = new parent(); var objproperty = new propertyobject();  myproperties[0] = objproperty; objparent.property = myproperties[0]; 

now when modify objparent.property not modify object in myproperties array, workaround? need don't have iterate on array.

this how modify object :

public void modifyobject(ref parent objecttomodify) {    objecttomodify.property.isthiscrazy = true; } 

then invoke modifyobject method.

structs meant immutable. assinging struct variable cause struct copied.

when assigning properties on 1 instance, properties of other other instance of struct aren't changed. hence, don't see updated in other reference.

sample code demonstrating problem structs:

struct x {     public string y { get; set; }      public x(string y) : this()     {         y = y;     } }  x x = new x("abc"); x x2 = x;  x2.y = "def";  console.writeline(x.y); console.writeline(x2.y); 

with classes you'd expected x.y , x2.y same, not structs.
