字符串格式帮助 [英] String Format help
问题描述
字符串格式公式写一个文本文件
下面对我不起作用
pos 1到10名
pos 15到30姓氏
pos 45到75岁工作
亚当史密斯程序员
string fmt =" {1,10} {15- 30} {45,75}" //没有任何帮助吗？
sb.Append（string.Format（fmt，Adam"，smith，progra mmer））;
嗨Matt，
首先，你使用String.Format函数都错了。请看下面的
：
http://msdn.microsoft.com/library/de...ormattopic.asp
你只能将一个字符串传递给函数。
假设你没有使用文字字符串，你应该能够
使用String.PadRight（）方法构建字符串。示例：
string firstName =" Adam";
string lastName =" Smith" ;;
string job =" ;程序员;
string together = firstName.PadRight（10）+ lastName.PadRight（30）+
job.PadRight（75）;

这对我有用：
Console.WriteLine（" 123456789a123456789b123456789c1 23456789d123456789e1234567
89f123456789g123456"）;
Console.WriteLine（" {0，-10} .... {1，-15} ............... {2，-30} |" ，Adam，
" Smith"，Programmer）;
在每个{n，m}中，第一个数字是参数的位置，第二个
数字是字段的长度，负数意义填充在右边
（正数会填充在左边）。

废话。您可以将任意数量的参数传递给String.Format，
，其中任何一个都可以是字符串。

string format formula to write a text file
below is not working for me
pos 1 to 10 name
pos 15 to 30 lastname
pos 45 to 75 job
Adam smith programmer
string fmt = "{1,10}{15-30}{45,75}" // is not working any help ?
sb.Append(string.Format(fmt,"Adam","smith","progra mmer"));
Hi Matt,
To start with, you''re using the String.Format function all wrong. Take a
look at the following:
http://msdn.microsoft.com/library/de...ormattopic.asp
You can only pass one string to the function.
Assuming that you''re not working with literal strings, you should be able to
use the String.PadRight() method to build you string. Example:
string firstName = "Adam";
string lastName = "Smith";
string job = "programmer";
string together = firstName.PadRight(10) + lastName.PadRight(30) +
job.PadRight(75);

This worked for me:
Console.WriteLine("123456789a123456789b123456789c1 23456789d123456789e1234567
89f123456789g123456");
Console.WriteLine("{0,-10}....{1,-15}...............{2,-30}|", "Adam",
"Smith","Programmer");
In each {n,m}, the first number is the position of the parameter, the second
number is the length of the field, negative meaning padded on the right
(positive numbers would pad on the left).

Nonsense. You can pass as many parameter as you like to String.Format,
and any of them can be strings.
