How to send extra parameter to wcf with optimize code ?

[Kuldeep]

Hi,

How to send extra parameter to wcf with optimize code ?
Now parameters are different category ??

I can not take array because these parameters are different category ?? 

public string X1{ get; set; }
public string X1{ get; set; }
public string X1{ get; set; }
..........................
..........................
..........................
..........................
public string X13{ get; set; }


public SchedulerInfoEntity(ISchedulerInfo baseInfo, string x1, string x2, string x3, string x4, string x5, int x6, int x7, bool blsX8, string x9, string x10, string x11,string x12,string 13)
            : base(baseInfo)
        { 
X1=x1;
X2=x2;
X3=x3;
...............................
...............................
...............................
...............................
X13=x13;
}

How will be managed a lot of parameter in the wcf 
Any better solution for fast processing???
