使用流编写器在C#中的同一行写入数字

Question

下面的代码给出了如下所述的OUTPUT1.如何实现OUTPUT2.

using (StreamWriter writer = new StreamWriter("testdata.txt", true))
{
    for (int i = 1; i <= 1500; i++)
    {                        
        writer.WriteLine(i +","); //OR  writer.Write(i + ",");
    }
}

输出1:

1,
2,
3,

输出2:

1,2,3,4,5,6

Answer 1

使用writer.Write而不是writer.Writeline避免额外的换行符.
