Question

我正在尝试通过csv上传一系列客户端信息，我在eginning中遇到了一些麻烦，但是之前的帖子已经回答了所以我能够开始读取数据然而它只读取了第一行。只是想知道是否有人有任何想法。我已经包含了以下代码

    private void btnUpload_Click(object sender, EventArgs e)
    {
         //Browse for file
        OpenFileDialog ofd = new OpenFileDialog();
        //Only show .csv files
        ofd.Filter = "Microsoft Office Excel Comma Separated Values File|*.csv";
        DialogResult result = ofd.ShowDialog();

        //If the user selects a valid file 
        if (result == DialogResult.OK)
        {
            //File is delimited by a comma
            char[] laClientDelim = { ',' };

            //New object for string manipulation
            objStringManipulation = new StringManipulation();

            // Parse the csv file
            List<string[]> lsClientList = objStringManipulation.parseCSV(ofd.FileName, laClientDelim);

            foreach (string[] laClient in lsClientList)
            {
                //Create new object for manipulating the database
                objSqlCommands = new SqlCommands("Client", "ClientName");



                string[] records = File.ReadAllLines(ofd.FileName); // read the file completely line by line
                char splitChar = ',';
                int splitCharCount = 0;
                int k = 0;


                    string[] fields = records[k].Split(splitChar);  // reads all the single values per line. 'splitChar' should be the delimiter.
                    splitCharCount++;
                    if (splitCharCount >= 4 && splitCharCount <= 10)
                    {
                        var stuff = from l in File.ReadLines(ofd.FileName)
                                    let x = l.Split(new[] { ',', ' ' },  StringSplitOptions.RemoveEmptyEntries)
                                              .Skip(1)
                                             .Select(s => char.Parse(s))
                                    select new
                                    {
                                        Client = x,
                                        ClientName = x
                                    };
                    }


                    //Inserts the client info into datbase
                objSqlCommands.sqlCommandInsertorUpdate("INSERT", records[k]);//laClient[0]);
                k++;
                    //Refreshs the Client table on display from the 
                    this.clientTableAdapter.Fill(this.kIIDImplementationCalcDataSet.Client);

                    //MAKE SURE TO ONLY ADD IN CLIENT AND CLIENT NAME 
                    //update the view 
                    dgvClientlst.Update() ; 





            }

        }
    }

Answer 1

你的循环基本上是这样的：

foreach (string[] laClient in lsClientList)
{
   int k = 0;
   string[] records = File.ReadAllLines(ofd.FileName);

   string[] fields = records[k].Split(splitChar);
   k++;
}

对于每个laClient，您的'k'值永远不会超过0。你需要在内部为每一行循环。

我知道我的答案并不完全符合您的要求，但如果将.csv文件转换为.xls文件，则可以非常轻松地对其进行操作。我已经多次这样做了，如果你愿意，我可以为你提供代码说明。

Answer 3

扩展Jonesy的答案（因为我还不能评论），在循环外声明变量k。它每次都被重置为零。

int k = 0;
foreach (string[] laClient in lsClientList)
{
    string[] records = File.ReadAllLines(ofd.FileName);

    string[] fields = records[k].Split(splitChar);
    k++;
}

csv文件只读取第一行
