C#

foreach (DataRow row in dt.Rows)
                    {
                        lstData.Add(new Tablelist() { FileName = csv.Replace(".csv", "").Replace(".CSV", ""), process = row["process"] + "", Event = row["Event"] + "", status = row["status"] + "" });

                    }
                }
                var RowNames = lstData.Select(k => k.FileName).Distinct();

                foreach (string rowName in RowNames)
                   
                    dtoutput.Rows.Add(rowName, typeof(string));

I'm getting this error "Input array is longer than the number of columns in this table" is it because I didn't add a column for this row, but when I add I still get this error .. can anyone guide me?..

Refer - [MSDN] Adding Columns to a DataTable[^]
You need to add the Columns for DataTable before adding Rows to that.

C#

dt.Columns.Add("Column1", typeof (string));
dt.Columns.Add("Column2", typeof (string));
dt.Columns.Add("Column3", typeof(string));
dt.Columns.Add("Column4", typeof(string));
