I want add every row data from csv into Dictionary in c#

csv is like that :

 - id,data 
 - 1,a  
 - 2,b

 Dictionary<int, string> m_dicTransactions = new Dictionary<int, string>();
 while ((line = sr.ReadLine()) != null)
                {
                    string[] columns = line.Split(',');

                    m_dicTransactions.Add(columns[0], columns[1]);

                }

您需要将第一列转换为整数：

m_dicTransactions.Add(int.Parse(columns[0]), columns[1]);
