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

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.

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...

@Shams: no, the values are coming from database, after I want to bind ValidValues to Dropdownlist. How can add string[] to existing objproductBL items?

If your Options are in dropdownlist than it means your value is not coming from dropdownlist so just add (value = "Red") vise versa in your all option.Hope this will work for you.
