输出文件写入数组到同一行

Question

我目前正在尝试将 2d int 数组写入文件。我已经将数据写入文件，但它们都出现在同一行上。

目前是这样显示的：

15101219816911171076171411881213567131441415101069101413878101181210156976139188711571210891267910

但我希望它看起来像这样：

15,10,12,19,8
16,9,11,17,10
7,6,17,14,11
8,8,12,13,5
6,7,13,14,4
1,4,15,10,10
6,9,10,14,13
8,7,9,10,11
8,12,10,15,6
9,7,6,13,9
18,8,7,11,5
7,12,10,8,9
12,6,7,9,10

这是我的代码。

        {
            StreamWriter outputfile;

            File.WriteAllText("ClosingStock.Txt", string.Empty);
            outputfile = File.AppendText("ClosingStock.Txt");

            for (int i = 0; i < (StockColumns); i++)
            {
                for (int j = 0; j < (StockRows); j++)
                {
                    outputfile.Write(Global_Stock[i , j]);
                }
            }
            outputfile.Close();
        }
       
        
    }

Any help with this problem would be much appreciated. Thanks.

Answer 1

你应该先创建一个字符串写入文件，然后一次性写入

StringBuilder sb = new StringBuilder();

for (int i = 0; i < (StockColumns); i++)
{
    for (int j = 0; j < (StockRows); j++)
    {
        sb.Append(Global_Stock[i , j]);
        sb.Append(",")
    }
}

File.WriteAllText("ClosingStock.Txt",sb.ToString());

Answer 2

只需在每个内循环后添加一个新行：

for (int i = 0; i < (StockColumns); i++)
{
    for (int j = 0; j < (StockRows); j++)
    {
        outputfile.Write(Global_Stock[i , j]);
    }
    outputfile.Write(Environment.NewLine);
}

如果我不得不猜测你应该在你的循环中切换 StockColumns 和 StockRows 以获得你想要的输出。另外，请参阅@Mihir Dave 以更好地实现将字符串写入文件。

Answer 3

        {
            StreamWriter outputfile;
            string comma = "";

            File.WriteAllText("ClosingStock.Txt", string.Empty);
            outputfile = File.AppendText("ClosingStock.Txt");

            for (int i = 0; i < (StockColumns); i++)
            {
                for (int j = 0; j < (StockRows); j++)
                {
                    outputfile.Write(comma);
                    outputfile.Write(Global_Stock[i , j]);
                    comma = ",";
                }
                comma = System.Environment.NewLine);
            }
            outputfile.Close();
        }
