需要帮助编辑 CSV 文件中的字段？

Question

我可以编辑每个字段，但这只适用于 CSV 文件的第一行。如果我尝试输入第二行或第三行等的患者 ID，它不会编辑任何数据。有人知道这是为什么吗？

我将这些行存储在一个字符串中，然后将它们分成另一个字符串中的不同字段，使用了一个 for 循环，我认为它会遍历每一行直到找到 ID。

        {
            string[] fields = lines[i].Split(','); // this here is splitting up each field, so ID,Name, Age will have their own index value

            if (fields[i] == ID) // this is where you will make the change, we need to determine the field here
            {               
                for (int k = 0; k <= fields.Length; k++)
                {
                    if(k == choice)
                    {
                        fields[k-1] = change;
                        Write.WriteLine(fields[0] + "," + fields[1] + "," + fields[2] + "," + fields[3] + "," + fields[4] + "," + fields[5]); // change is made
                    }
                }           
            }
            else
            {
                if (!edited)
                {
                    Write.WriteLine(fields[0] + "," + fields[1] + "," + fields[2]+ "," + fields[3] + "," + fields[4] + "," + fields[5]); // if not edited then it will print the line to the temp file                   
                }
            }                                 
        }
        Write.Close();
        File.Delete("patinfo.csv");
        System.IO.File.Move("temp.csv", "patinfo.csv");                                 
        Console.ReadLine();

Answer 1

if (fields[0] == ID) // replaced i with 0
{
    for (int k = 1; k <= fields.Length; k++) // replaced 0 with 1

提示：检查'change'，如果不在[1,6]中，则该行未写入
