本文介绍了变量String.Format长度的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我有以下代码:
解决方案格式字符串也只是字符串 - 您可以分别定义格式:
int n = 3;
string format = string.Format({{0,{0}}},n);
//更可读:string format ={0,+ n +};
var output = string.Format(format,str);
编辑:
看起来像你想要的也可以通过:
var str =ABC;
string output = str.PadLeft(7);
I have the following code:
var str = "ABC"; var n = 7; var output = String.Format("{0,n}", str);This should output the string
" ABC"How should I change the line above?
解决方案Format strings are just strings too - you can define the format separately:
int n = 3; string format = string.Format("{{0,{0}}}", n); //or more readable: string format = "{0," + n + "}"; var output = string.Format(format, str);Edit:
After your update it looks like what you want can also be achieved by PadLeft():
var str = "ABC"; string output = str.PadLeft(7);
