问题描述

我试图导出我的C＃列表到CSV文件。全部设置好。但事实是场分离器工作不正常。它显示像，我的字符串结尾（例如：0000324df）。这是我的控制器code。

 的IEnumerable stockexpo = stockexp; //赋值
        MemoryStream的输出=新的MemoryStream（）;
        StreamWriter的作家=新的StreamWriter（输出，Encoding.UTF8）;
        writer.Write（货号，）;
        writer.Write（重复计数）;
        writer.WriteLine（）;
        的foreach（在stockexpo StockResult顺序）
        {
            writer.Write（的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;        返回文件（输出，文/逗号分隔值，stockexp.csv）;

我需要知道我可以适当地单独的字段值。任何人都可以帮我的。

解决方案

  writer.Write（\\）;

code的这条线将是一个每次都输。为什么它在所有？

另外，我不会有的WriteLine前一逗号，因为没有必要限定该文件的末尾。

 的IEnumerable stockexpo = stockexp; //赋值
    MemoryStream的输出=新的MemoryStream（）;
    StreamWriter的作家=新的StreamWriter（输出，Encoding.UTF8）;
    writer.Write（货号，）;
    writer.Write（重复计数）;
    writer.WriteLine（）;
    的foreach（在stockexpo StockResult顺序）
    {
        writer.Write（order.ItemNumber）;
        writer.Write（，）;
        writer.Write（order.Count）;
        writer.WriteLine（）;
    }
    writer.Flush（）;
    output.Position = 0;    返回文件（输出，文/逗号分隔值，stockexp.csv）;

I was trying to export my C# list to Csv file. All is set well. But the thing is field seperator is not working properly. its showing like, my string with " at the end (eg: 0000324df"). Here is my Controller code.

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");

I need to know how i can seperate the field values appropriately. Anyone can help me for this.

解决方案

  writer.Write("\"");

This line of code will be outputting a " every time. Why have it at all?

Also, I wouldn't have a comma before the WriteLine, since there is no need to delimit the end of the file.

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");
