下面是用于解析csv文件并使用客户端和客户端名称填充 2X2 表的按钮的代码。我在网上查看过，但找不到合适的示例来说明我想做的事情，使用 VS 2012 和 C# 我想通读文件，只取出并插入客户端和客户端名称，但目前我的代码只需要一切文件内。

如果找到关键字，我的预期方法是csv阅读并阅读它；使用它然后继续搜索，只是想知道是否有人可以告诉我如何？

例如，我想在laClient列表中进行搜索，如果我发现HTY我想在此之后获取接下来的 6 个字符并继续我的搜索。

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");
            laClient[8].
                

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

            //update the view 
            dgvClientlst.Update(); 
            
        }
    }
}

csv 数据看起来像这样（下图），由于这个布局的质量很差，我试图附上一张图片以提高可读性，但我没有 10 名声望，所以我无法这样做。

您应该能够读取 csv，并使用以下代码获取单个值：

string[] records = File.ReadAllLines(fileName); // read the file completely line by line

// loop through all lines
foreach (string record in records)
{
    string[] fields = record.Split(splitChar);  // reads all the single values per line. 'splitChar' should be the delimiter.
}
