定义具有大量属性的默认类属性的最佳方法

Question

What is the best to define default class properties when you have large number of class properties and the default value of ever property is same.Can we do looping to set the default value in such cases. If yes how can we do that.

public class PathologyTest
{
    public string testId { get; set;}
    public string testName { get; set;}
    public string testDate { get; set;}
    public string testType { get; set;}
    ...
}

Similarly there are around 150 properties of the class and the default value of every property is "invalid patient".

Currently I am doing [System.ComponentModel.DefaultValue("invalid patient")] for each property. Is there any way of looping to set the default value. Please suggest what is the best way?

Answer 1

• C# 5 and earlier : You have to set them in constructor.
• C# 6 : You can set default value like public int X { get; set; } = x; public int X { get; set; } = x; ( Languages features in C# 6 and VB 14 )

Answer 2

So 150 properties
Someone can look at the code and know what it is doing

private string defaultValue = "default value"
private string testID = defaultValue;
public string TestId 
{ 
    get
    {
        return testID;
    }
    set 
    {
        testID = value;
    }
}
