C# operation CSV file class example

This article describes the C# operation of CSV file classes. Share it for your reference. The specific analysis is as follows:

This C# class is used to convert DataTable to CSV files and CSV files into DataTable. If you need to convert between CSV and DataTable, this class is very suitable.

namespace 
{
 /// &lt;summary&gt;
 /// CSV file conversion class /// &lt;/summary&gt;
 public static class CsvHelper
 {
  /// &lt;summary&gt;
  /// Export the report as Csv  /// &lt;/summary&gt;
  /// &lt;param name="dt"&gt;DataTable&lt;/param&gt;

  {
   try
   {
    string strBufferLine = "";
    StreamWriter strmWriterObj = new StreamWriter(strFilePath, false, .UTF8);
    (tableheader);
    (columname);
    for (int i = 0; i &lt; ; i++)
    {
     strBufferLine = "";
     for (int j = 0; j &lt; ; j++)
     {
      if (j &gt; 0)
       strBufferLine += ",";
      strBufferLine += [i][j].ToString();
     }

      dr[i] = split[i];
     }

   }
   return dt;
  }
 }
}
