Question

I am trying to read a string into an array and I get the error “Cannot implecitly convert type ‘string’ to ‘string[]’.

The error occurs here:

string[] sepText = result.Tables[0].Rows[0].Field<string>("WebHTML").UrlDecode();

My full if else statement is below:

if (!string.IsNullOrEmpty(result.Tables[0].Rows[0].Field<string>("WebHTML")))
            {
                string[] sepText = result.Tables[0].Rows[0].Field<string>("WebHTML").UrlDecode();
                NewsContent.Text = sepText[1];
                if (!string.IsNullOrEmpty(sepText[0]))
                    Image1.ImageUrl = sepText[0];
                else
                    Image1.Visible = false;
                NewsTitle.Text = String.Format("<a href=\"{0}/news/{1}/{2}.aspx\">{3}</a>", Extensions.GetServerName(true), result.Tables[0].Rows[0].Field<int>("News_Item_ID"), result.Tables[0].Rows[0].Field<string>("Title").UrlFormat(), result.Tables[0].Rows[0].Field<string>("Title"));
                Hyperlink1.NavigateUrl = String.Format("{0}/news/{1}/{2}.aspx", Extensions.GetServerName(true), result.Tables[0].Rows[0].Field<int>("News_Item_ID"), result.Tables[0].Rows[0].Field<string>("Title").UrlFormat());
            }
            else
            {
                Hyperlink1.Visible = false;
                Image1.Visible = false;
            }

Thank you for your help!

EDIT Code for URL Decode:

public static string UrlDecode(this string str)
{
    return System.Web.HttpUtility.UrlDecode(str);
}

Answer 1

result.Tables[0].Rows[0].Field<string>("WebHTML") is going to give you the value of the WebHTML field in the first row in the first table which is a single string rather than a string[].

You may want to show your code for UrlDecode() since it looks like a custom implementation rather than one of the built-in framework versions.

You also declare the UrlDecode method to take a string as a parameter and return a string. Remember, a string is not the same thing as a string array.
