Problem

The class representation in the debugger, string parameters, and log files is illegible and you want to customize its appearance.

Solution

Here’s a class with a custom ToString method:

using System; using System.Text; namespace Section_03_06 { class Order { public int ID { get; set; } public string CustomerName { get; set; } public DateTime Created { get; set; } public decimal Amount { get; set; } public override string ToString() { var stringBuilder = new StringBuilder(); stringBuilder.Append(nameof(Order)); stringBuilder.Append(" {
"); if (PrintMembers(stringBuilder)) stringBuilder.Append(" "); stringBuilder.Append("
}"); return stringBuilder.ToString(); } protected virtual bool PrintMembers(StringBuilder builder) { builder.Append(" " + nameof(ID)); builder.Append(" = "); builder.Append(ID); builder.Append(",
"); builder.Append(" " + nameof(CustomerName)); builder.Append(" = "); builder.Append(CustomerName); builder.Append(",
"); builder.Append(" " + nameof(Created)); builder.Append(" = "); builder.Append(Created.ToString("d")); builder.Append(",
"); builder.Append(" " + nameof(Amount)); builder.Append(" = "); builder.Append(Amount); return true; } } }

Here’s an example of how that’s used:
