Indent String with Spaces

This example shows how to indent strings using method for padding in C#. To repeat spaces use method String.PadLeft. If you call „hello“.PadLeft(10) you will get the string aligned to the right: „     hello“. If you use empty string instead of the „hello“ string the result will be 10× repeated space character. This can be used to create simple Indent method.

相应的可以使用String.PadRight实现右边填充固定位数的指定字符

The Indent method:

[C#]

public static string Indent(int count){    return "".PadLeft(count);}

Test code:

[C#]

Console.WriteLine(Indent(0) + "List");Console.WriteLine(Indent(3) + "Item 1");Console.WriteLine(Indent(6) + "Item 1.1");Console.WriteLine(Indent(6) + "Item 1.2");Console.WriteLine(Indent(3) + "Item 2");Console.WriteLine(Indent(6) + "Item 2.1");

Output string:

List   Item 1      Item 1.1      Item 1.2   Item 2      Item 2.1

C#输出文本树形层次，前或者后自定义空格位数
