泛型在CVS数据读取中的应用

代码

public List<Dictionary<string, string>> GetData(string filePath, out List<string> Column)
        {
            Column = new List<string>();
            List<Dictionary<string, string>> Data = new List<Dictionary<string, string>>();
            string strLine = "";
            string[] strArray;
            StreamReader sr = new StreamReader(filePath);
            strLine = sr.ReadLine();
            if (strLine == null || strLine == "")
            {
                return new List<Dictionary<string, string>>();
            }
            strArray = strLine.Split(',');
            foreach (string item in strArray)
            {
                Column.Add(item);
            }
            strLine = sr.ReadLine();
            while (strLine != null)
            {
                strArray = strLine.Split(',');
                Dictionary<string, string> dict = new Dictionary<string, string>();
                for (int i = 0; i < Column.Count; i++)
                {
                    dict.Add(Column[i], strArray[i]);
                }
                Data.Add(dict);
                strLine = sr.ReadLine();
            }
            sr.Close();
            return Data;
        }

调用方法如下：

List<string> Column;
            List<Dictionary<string, string>> Date = GetData(this.textBox1.Text.Trim(), out Column);
            string str = "";
            foreach (Dictionary<string, string> item in Date)
            {
                foreach (string item1 in Column)
                {
                    str += item[item1] + "   ";
                }
                str += Environment.NewLine;

            }
            this.textBox2.Text = str;
