Convert list of string to DataTable
-1
I want to convert List of string to datatable so I try:
List<string> DesignNameList = new List<string>();
public static Mymethod...{
parameters = ToDataTable(DesignNameList);
}
public static DataTable ToDataTable(List<string> list)
{
DataTable dataTable = new DataTable();
foreach (var row in list)
{
dataTable.Rows.Add(row);
}
return dataTable;
}
But I get error when foreach is being executed in line dataTable.Rows.Add(row);:
'Input array is longer than the number of columns in this table.'
What I'm doing wrong? Regards

There is little reason to do such a thing. A List<T> is probably a bit more flexible than a DT...and you certainly do not need a DataTable you created for DB updates

You'll need to add a column to the data table first. As it is created is has no columns
DataTable datatable= new DataTable();
DataColumn workCol = datatable.Columns.Add("column_name", typeof(String));

Try to exchange the loop 'foreach' by the 'for', like this:
DataTable dataTable = new DataTable();
for (int i = 0; i < list.Count(); i++)
{
dataTable.Rows.Add(list[i]);
}
return dataTable;
