What is wrong in the code below?

using System;

namespace ConsoleApplication2
{
class Trial
{
static void Main(string[] args)
{
MutStruct ms;
ms.partNo = "xxx";
MutTransform mt = new MutTransform(ms.partNo);// errors here "cannot
convert from string to... etc."
Console.WriteLine(mt.PartNumber);
}
}

internal struct MutStruct
{
internal string partNo;
}

internal struct MutTransform
{
internal string PartNumber;
internal MutTransform(MutStruct mstr)
{
this.PartNumber = mstr.partNo.PadLeft(10, 'y');
}
}
}

You are passing ms.partNo, which is a string to MutTransform constructor.

I think you may want to do something like this:

MutTransform mt = new MutTransform(ms) instead;

Hello Adrian,

A> MutTransform mt = new MutTransform(ms.partNo);//

here you set the string as the param of your ctor

A> internal MutTransform(MutStruct mstr)

and there the constructor that takes the struct, not the string

Besides the fact that you appear to be using "struct" in an odd way....

The error message you're receiving is correct. ms.PartNo is a string,
but the constructor for MutTransform accepts a MutStruct, not a string.
You should make one of two changes. Either:

MutTransform mt = new MutTransform(ms);

or, down in MutTransform:

internal struct MutTransform
{
internal string PartNumber;
internal MutTransform(string partNo)
{
this.PartNumber = partNo.PadLeft(10, 'y');
}
}

One or the other. By the way, what's the point of wrapping a string in
a struct? Or is this is a pared-down version of what's really going
on...?

Ohoh.

Thank you,
Adrian.

Yes it is.
