How to get string array value to existing list c# ?

Question

Hello Everyone,

 

I have list items inside objproductBL object.

List objproductBL = new List();
            objproductBL = objProductDAL.GetProductSpecificaton(productid).Select(item => new ProductItemsBL
           {
               ProductCategoryName = item.ProductCategoryName,
               ProductName = item.ProductName,
               AttributeName = item.AttributeName,
               ProductImage1 = item.ProductImage1,
               ValidValues = item.ValidValues,
               ProductDescription = item.ProductDescription,
               AttributeMaxLength = item.AttributeMaxLength,
               AttributeControlType = item.AttributeControlType
            }).ToList();

 

 

From the list, if the 'AttributeControlType' contain "DropDownList" then I want to show it's 'ValidValues' inside drowpdownlist.

 

 

 

 

 For this, I have tried created a string[] inside model class.

public class Mymodel
    {
 public string[] arryvalidvalue = new string[] { };
}

 Then, implement code like this

 

List objproductBL = new List();
            objproductBL = objProductDAL.GetProductSpecificaton(productid).Select(item => new ProductItemsBL
           {
               ProductCategoryName = item.ProductCategoryName,
               ProductName = item.ProductName,
               AttributeName = item.AttributeName,
               ProductImage1 = item.ProductImage1,
               ValidValues = item.ValidValues,
               ProductDescription = item.ProductDescription,
               AttributeMaxLength = item.AttributeMaxLength,
               AttributeControlType = item.AttributeControlType
            }).ToList();

           ProductItemsBL objBL = new ProductItemsBL();
           /*ListValidValues*/
           bool yesno = false;
           foreach (var item in objproductBL)
           {
               for (int i = 0; i < item.ValidValues.Length; i++)
               {
                   if (item.ValidValues.Substring(i, 1) == ",") yesno = true;
               }
               if (yesno == true)
               {
                   objBL.arryvalidvalue = (item.ValidValues.Split(new[] { "," }, StringSplitOptions.RemoveEmptyEntries));
                   yesno = false;
               }
           }

          // objproductBL.AddRange()
           return objproductBL;

 But inside 'return objproductBL' getting null 'arryvalidvalue' object. How can I get value?

 

Please help me...
