Struct cannot contain parameterless constructor

• Apr 29, 2019

CodeRush Classic shows the Struct cannot contain parameterless constructor code issue if a struct constructor does not have parameters.

Fix

Add the required parameters to the struct constructor.

Purpose

Highlights the struct constructor declarations, which would cause the Structs cannot contain explicit parameterless constructors compilation error.

Example

C#

public struct UserInfo
{
    public │UserInfo()
    {
        Name = string.Empty;
        FamilyName = string.Empty;
        BirthDate = DateTime.MinValue;
        Phone = string.Empty;
    }
    public string Name { get; set; }
    public string FamilyName { get; set; }
    public DateTime BirthDate { get; set; }
    public string Phone { get; set; }
}

Fix:

C#

public struct UserInfo
{
    public UserInfo(string name, 
        string familyName, 
        DateTime birthDate, 
        string phone)
    {
        Name = name;
        FamilyName = familyName;
        BirthDate = birthDate;
        Phone = phone;
    }
    public string Name { get; set; }
    public string FamilyName { get; set; }
    public DateTime BirthDate { get; set; }
    public string Phone { get; set; }
}
