C# - split method - cannot convert char to string

[DaveRook]

Hi

I've had a few error messages with this I don't understand why. It works fine in a Windows Form, but now moving it to a website, it's not working. I don't have the option to count the lines as I did with Windows Forms so I assume the best way is to use the split method. However, the split method only returns Character Arrays, and I want a string, so am calling the split from the Text.RegularExp ression namespace.

I am trying to split the lines entered into a multiline textbox line by line, and then peform some logic in each array.

I am told it can't convert char to string.

My code

            string[] arrS = System.Text.RegularExpressions.Regex.Split(txtS.Text,Environment.NewLine);
            foreach(string st in Convert.ToString(arrS))
            {
                     //code
            } 
 

Any ideas what I've done wrong? Or is the foreach loop only reads strings?

It should have ideally been as below:

foreach(string st in arrS)
{
//code
}

I did that originally, same error. I only added the Convert.ToStrin g due to the cannot convert type char to string error message.

Any other ideas?

Are you sure the error you recieved before adding Convert.ToStrin g was on the line you modified? I can't see how an element of string[] would ever be treated as a char. Anyway, instead of using regex, why don't you just use the split method built into the string class:

string[] arrS = txtS.Text.Split(new string[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries);
foreach(string s in arrS)
{
 
}
