c# - 将字符串列表转换为数据表

Question

我想将字符串列表转换为数据表，所以我尝试:

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;

        }

但是当在 dataTable.Rows.Add(row); 行执行 foreach 时出现错误:

'Input array is longer than the number of columns in this table.'

我做错了什么？问候

您需要首先向数据表添加一列。创建时没有列

DataTable datatable= new DataTable();  

DataColumn workCol = datatable.Columns.Add("column_name", typeof(String));
