Dumping array using Windbg

Question

In C#,I have an object say Shape which has two fields area and length.

I got a shapeList which is a collection of Shapes.

I have got a shapeList address in my crash dump.

I need a script in windbg that iterates through each item in the shapeList array and display the value of area alone for each shape.

Answer 1

    .for ( r $t1 = 0; @$t1 < [length] * [element size]; r $t1 = @$t1 + [element size];) {!do poi(poi(@$t1+poi([address of list]+0x8)+0x18)+[offset of child object in parent object) }

    For example:

     class Foo
        {
            public Bar MyBar { get; set; }
        }

        class Bar
        {
            public String MyString { get; set; }
        }
