在 Console.WriteLine 方法中格式化字符串 [英] Format Strings in Console.WriteLine method

问题描述

我是 C# 编程新手.谁能解释一下下面的代码:

Im new to C# programming. Can someone please explain the following code:

Console.WriteLine( "{0}{1,10}", "Face", "Frequency" ); //Headings
Console.WriteLine( "{0,4}{1,10}",someval,anotherval);

我知道这会打印带有给定标题的两列值，并且 {0} 指的是给定的第一个参数.但是 {x,y} 形式的格式字符串是什么意思呢?

I understand that this prints two columns of values with the headings given, and {0} refers to the first argument given. But what is the meaning of the format strings of the form {x,y} ?

推荐答案

向左添加填充.以下备忘单对于记住各种字符串格式模式非常有用:

It adds padding to the left. Very useful for remembering the various string formatting patterns is the following cheat sheet:

.NETString.Format 备忘单

正值向左添加内边距，负数向右侧添加内边距

Positive values add padding to the left, negative add padding to the right

Sample                                 Generates
String.Format("[{0, 10}]", "Foo");     [∙∙∙∙∙∙∙Foo]
String.Format("[{0, 5}]", "Foo");      [∙∙Foo]
String.Format("[{0, -5}]", "Foo");     [Foo∙∙]
String.Format("[{0, -10}]", "Foo");    [Foo∙∙∙∙∙∙∙]
