در اینجا مقدار Hex برایمان قابل فهم نیست. سناریویی را در نظر بگیرید که مقادیر باید داخل دیتابیس به صورت Hex نگهداری شوند، اما می‌خواهیم هنگام دیباگ، مقدار پراپرتی HexValue به صورت قابل درک و decimal آن نمایش داده شود.

برای انجام اینکار میتوانیم از DebuggerTypeProxy استفاده کنیم. ابتدا کلاسی ایجاد میکنیم که بعنوان proxy، مقادیر را به شکلی که نیاز داریم نمایش دهد. این کلاس object اصلی را در Constructor دریافت کرده و مقادیر مورد نظرمان، از طریق property هایی که در آن تعریف می‌کنیم قابل دسترسی هستند:

public class DataDebugView
{
    private readonly Data _data;

    public DataDebugView(Data data)
    {
        _data = data;
    }

    public string DecimalValue
    {
        get
        {
            bool isValidHex = int.TryParse(_data.HexValue, System.Globalization.NumberStyles.HexNumber, null, out var value);
            return isValidHex ? value.ToString() : "INVALID HEX STRING";
        }
    }
}

در نهایت برای اعمال کردن این کلاس proxy، از ویژگی DebuggerTypeProxy بر روی کلاس اصلی استفاده می‌کنیم:

[DebuggerTypeProxy(typeof(DataDebugView))]
public class Data
{
    public string Name { get; set; }

    public string HexValue { get; set; }
}

بعد از اعمال تغییرات و اجرای دوباره برنامه، نحوه نمایش مقادیر کلاس به این صورت تغییر خواهند یافت:
