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}
?
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]
