如何打印列表作为表中的控制台应用程序？ [英] How to print List as table in console application?

问题描述

我需要的方法来打印列表作为表中的控制台应用程序和preVIEW在方便的格式是这样的：

  Pom_No ITEM_ code ordered_qty received_qty

1011 ITEM_ code1 ordered_qty1 received_qty1

1011 ITEM_ code2 ordered_qty2 received_qty2

1011 ITEM_ code3 ordered_qty3 received_qty3

1012 ITEM_ code1 ordered_qty1 received_qty1

1012 ITEM_ code2 ordered_qty2 received_qty2

1012 ITEM_ code3 ordered_qty3 received_qty3
 

解决方案

您主要手段将是

  Console.WriteLine（{0,5} {1,10} {2} -10，S1，S2，S3）;
 

在 5 和 10 的宽度说明。使用负值左对齐。

格式也是可能的：

  Console.WriteLine（Y = {0,12：＃，## 0.00}，Y）;
 

或24和自定义格式宽度的日期：

 的String.Format（现在= {0,24：DD HH：MM：SS}，DateTime.Now）;
 

---

编辑，对于C＃6

通过串插您现在还可以写

  Console.WriteLine（${s1,5} {s2,10} {S3，-10}）;
Console.WriteLine（$Y = {Y，12＃，## 0.00}）;
的String.Format（$现在= {DateTime.Now，24：DD HH：MM：SS}）;
 

此并不限于只是的WriteLine（）或的ToString（）

 字符串s = $现在= {DateTime.Now，24：DD HH：MM：SS}++ $Y = {Y，12：＃，＃ ＃0.00};
 

I need Method to print List as table in console application and preview in convenient format like this:

Pom_No          Item_Code          ordered_qty                      received_qty

1011            Item_Code1         ordered_qty1                    received_qty1 

1011            Item_Code2         ordered_qty2                    received_qty2

1011            Item_Code3         ordered_qty3                    received_qty3

1012            Item_Code1         ordered_qty1                    received_qty1 

1012            Item_Code2         ordered_qty2                    received_qty2

1012            Item_Code3         ordered_qty3                    received_qty3

解决方案

Your main tool would be

Console.WriteLine("{0,5} {1,10} {2,-10}", s1, s2, s3);  

The ,5 and ,10 are width specifiers. Use a negative value to left-align.

Formatting is also possible:

Console.WriteLine("y = {0,12:#,##0.00}", y);

Or a Date with a width of 24 and custom formatting:

String.Format("Now = {0,24:dd HH:mm:ss}", DateTime.Now);

---

Edit, for C#6

With string interpolation you can now also write

Console.WriteLine($"{s1,5} {s2,10} {s3,-10}");  
Console.WriteLine($"y = {y,12:#,##0.00}");
String.Format($"Now = {DateTime.Now,24:dd HH:mm:ss}" );

this is not restricted to just WriteLine() or ToString()

string s = $"Now = {DateTime.Now,24:dd HH:mm:ss}" + " " + $"y = {y,12:#,##0.00}" ;
