读取文本文件时出现问题将其保存到C＃中的csv文件中？

我的文本文件格式如下。我将保存到c＃中的csv文件中。

//需要忽略人员清关对行，文本文件中的凭证行。

Access.text文件：

名称：，4楼，IT

人员清关对

清关名称：，iT

凭证

卡号：，1234



姓名：，Graham，John

人员清关对

清仓名称：，Temps

我正在循环文本文件中下面

Hi ,

I have text file format like below. I am saving into csv file in c#.
//need to ignore Personnel Clearance Pair line,Credential line in the text file.
Access.text file:
Name:,4th Floor, IT
Personnel Clearance Pair
Clearance name:,iT
Credential
Card number:,1234

Name:,Graham, John
Personnel Clearance Pair
Clearance name:,Temps
Credential
Card number:,23489

I am looping throught the text file like below

try
 {
System.IO.TextWriter Summarytw = System.IO.File.CreateText(sOutputFilePath + sOutFileName_DST);

//Here I am adding column names to csv file(output file).
                string line1 = string.Empty;
                string strColumnname = string.Empty;//{"Name","Clearance name","Card number"};
                strColumnname = "Name,Clearance name,Card number";
                string[] arr = strColumnname.Split(',');
                int a = arr.Length;

                for (int y = 0; y < arr.Length; y++)
                {
                    line += arr[y].ToString() + ",";
                }
                Summarytw.WriteLine(line);

//here I am reading the text file(input file)
  using (System.IO.StreamReader sr = new System.IO.StreamReader(sInputPath + sInFile))
                {

                    while ((line = sr.ReadLine()) != null)
                    {
//I need to save only name, clearance name, card number values to the csv file.
 if ((line.Contains("Name")) || (line.Contains("Clearance name")) || (line.Contains("Card number")))
                        {
                            string s = line.ToString();
                            string pattern = ":,";
                            string strdelimiter = ",";
                            string[] substrings = Regex.Split(line, pattern);
                            for (int i = 1; i < substrings.Length; i++)
                            {
                                string value = substrings[1].ToString();
                                if (i == substrings.Length)
                                {
                                    strconcat += " " + value + " ";
                                }
                                else
                                {
                                    strconcat += "\" " + value + "\"";
                                    strconcat += strdelimiter;
                                }

                            }


                        }


                        if (line.StartsWith("Card number"))
                        {
                            strconcat += Environment.NewLine;
                        }


                    }

                    Summarytw.WriteLine(strconcat);
                }
}

for Access.txt代码中的上述行它工作正常。



但如果数据如下所示

for the above line in Access.txt code it was working fine.

but if the data is like below

Name:,lori, Julie
Personnel Clearance Pair
Clearance name:,Access Full Time Employees //No card number row
Credential 

Name:,Badge 43511, Visitor
Personnel Clearance Pair//No clearance name row
Credential
Card number:,43511

如果有没有卡号或清关名称csv文件如下所示。

ACCESS.CSV：

名称清关名片号码

4楼， IT iT 1234

格雷厄姆，John Temps 23489

lori，Julie Access（如果没有卡号，则附有下一条记录详情）

徽章56892 56892（如果清关名称为空，则卡号将保存到csv文件中的清除名称字段中。）


文本文件数据是逐行的。

尝试了很多但失败了。

搜索在谷歌，但没有找到正确的答案。

请帮帮我。

ACCESS.CSV:
Name Clearance name card number
4th Floor, IT iT 1234
Graham, John Temps 23489
lori, Julie Access (if no card number it is placing with next record details)
Badge 56892 56892 (if clearance name is empty then card number Is saving into clearance name field in csv file.)

The text file data is line by line .
