Structs cannot contain explicit parameterless constructors

hi,

when you do a object language you use a class it is better

 public class emp
{
  private int empno;
  private string ename;

  public emp(int no, string nam)
  {
    empno = no;
    ename = nam;
  }
  public  emp (int e)
  {
    empno = e;
    ename = "mostafa";
  }
  public emp() //  why give me error  in this contractor
  {
    empno = 0;
    ename = "mostafa";
  }

  public int Mpno
  {
    get
    {
      return empno;
    }
  }

  public string Name
  {
    get
    {
      return ename;
    }
  }

Hi.
Each struct already has a default constructor that initializes the object to zero. Therefore, the constructors that you can create for a struct must take one or more parameters.

public struct ClassY
{
   public int field1;
   public ClassY(){}   // CS0568, cannot have no param constructor
   // Try following instead:
   // public ClassY(int i)
   // {
   //    field1 = i;
   // }
}

public class ClassX
{
   public static void Main()
   {
   }
}

sustituye el constructor sin parametros public, por static.

struct emp
{
public int empno;
public string ename;

public emp(int no, string nam)
{
empno = no;
ename = nam;
}

public emp (int e)
{
empno = e;
ename = "mostafa";
}

static emp() // why give me error in this contractor
{
empno = 0;
ename = "mostafa";
}
}
