Here is the snippet which can be used to count total columns in your flat file. Below script assume that you have column count based on separator=comma. if you use different separator then just change script accordingly

        public void Main()
        {
            // TODO: Add your code here

            var colCnt = GetFileColumns("file1",',');
            MessageBox.Show("Your file has total " + colCnt + " columns");
            Dts.TaskResult = (int)ScriptResults.Success;
        }
        private int GetFileColumns(string connName,char colSeperator= ',')
        {
            var filePath=Dts.Connections[connName].ConnectionString;
            string firstline;
            using (System.IO.StreamReader sr = new System.IO.StreamReader(filePath))
            {
                 firstline= sr.ReadLine();
            }              
            var colArr=firstline.Split(new char[]{colSeperator});
            return colArr.Length;
        }

public void Main()

{

// TODO: Add your code here

var colCnt = GetFileColumns("file1",',');

MessageBox.Show("Your file has total " + colCnt + " columns");

Dts.TaskResult = (int)ScriptResults.Success;

}

private int GetFileColumns(string connName,char colSeperator= ',')

{

var filePath=Dts.Connections[connName].ConnectionString;

string firstline;

using (System.IO.StreamReader sr = new System.IO.StreamReader(filePath))

{

firstline= sr.ReadLine();

}

var colArr=firstline.Split(new char[]{colSeperator});

return colArr.Length;

}
