Count the Number of elements in a string Array c# [duplicate]

Question

I am reading in data from a file into a list. Once I have the data read in, I would like to split every string, and display the length of the split string. I have tried string.Length and string.Count, but nothing works. How can I find the number of elements in my split string?

Here is the section of relevant code:

string fileread = openFileDialog1.Filename; //Opens file from computer lines = System.IO.File.ReadAllLines(fileread); foreach (string line in lines) { string[] Data_array = line.Split(','); List<string> Data_list = new List<string>(); Data_list.Add(line); lbl_datacolumns.Text = Data_array.Count;//should show number of elements in Data_array }

The error is: "Cannot Convert method group 'Count; to non-delegate type 'string'

What part of this doesn't work? If you want the cumulative count, then you'll have to sum the individual lengths. — Sami Kuhmonen

@DStanley That's alright, I only need the last one, all lines should be equal length. The problem is: "Cannot Convert method group 'Count; to non-delegate type 'string'" — manateejoe

Try to search. Count() is a (extension) method, so you need to add parentheses to make it a method call. See Cannot convert method group 'ToList' to non-delegate type. Then you get an int that you want to assign to a string. For that see Convert int to string? or just put the compiler error you get in your favorite web search engine. — CodeCaster

@CodeCaster Do I need to convert Data_array into an int before applying Count()? — manateejoe

Use the Length property:

lbl_datacolumns.Text = Data_array.Length.ToString();

That still gives me the error: Cannot convert Method group 'ToString' to non-delegate type 'string'.....

@manateejoe then you again think you can omit the parentheses from a method call. You can't, this isn't Visual Basic.

@CodeCaster I have added the parentheses and I am still getting the error EDIT: Never mind, restarting the program helped. Thanks!
