将C＃列表导出到Csv文件

Question

我试图将我的C＃列表导出为Csv文件。一切都很好。但是现场分隔器不能正常工作。它显示的像我的字符串“最后（例如：0000324df”）。这是我的控制器代码。

IEnumerable stockexpo = stockexp; // Assign value 
     MemoryStream output = new MemoryStream(); 
     StreamWriter writer = new StreamWriter(output, Encoding.UTF8); 
     writer.Write("ItemNo,"); 
     writer.Write("Repeat Count"); 
     writer.WriteLine(); 
     foreach (StockResult order in stockexpo) 
     { 
      writer.Write(String.Format("{0:d}", order.ItemNumber)); 
      writer.Write("\""); 
      writer.Write(","); 
      writer.Write("\""); 
      writer.Write(order.Count); 
      writer.Write("\""); 
      writer.Write(","); 
      writer.WriteLine(); 
     } 
     writer.Flush(); 
     output.Position = 0; 

     return File(output, "text/comma-separated-values", "stockexp.csv"); 

我需要知道我如何能够适当地分离字段值。任何人都可以帮助我。

Answer 1

writer.Write("\""); 

这行代码将是一个“每次输出。为什么它呢？

而且，我不会有之前的WriteLine一个逗号，因为没有必要划定该文件的末尾。

IEnumerable stockexpo = stockexp; // Assign value 
    MemoryStream output = new MemoryStream(); 
    StreamWriter writer = new StreamWriter(output, Encoding.UTF8); 
    writer.Write("ItemNo,"); 
    writer.Write("Repeat Count"); 
    writer.WriteLine(); 
    foreach (StockResult order in stockexpo) 
    { 
     writer.Write(order.ItemNumber); 
     writer.Write(","); 
     writer.Write(order.Count); 
     writer.WriteLine(); 
    } 
    writer.Flush(); 
    output.Position = 0; 

    return File(output, "text/comma-separated-values", "stockexp.csv");
