在.net中替代string.Format（“... {0} ... {1} ...”，v1，v2）(alternatives to string.Format(“… {0}…{1}…”,v1,v2) in .net?)

在.net中替代string.Format（“... {0} ... {1} ...”，v1，v2）(alternatives to string.Format(“… {0}…{1}…”,v1,v2) in .net?)

带有“bla {0} bla”语法的string.Format（）非常棒。 但有时我不想枚举占位符。 相反，我只是想在变量中依次映射变量。 有没有可以做到这一点的图书馆？

例如，而不是

string.Format("string1={0}, string2={1}", v1, v2)

就像是

string.Format("string1={*}, string2={*}", v1, v2)

string.Format() with it's "bla {0} bla" syntax is great. But sometimes I don't want to enumerate the placeholders. Instead I just want to map the variables sequentially in the placeholders. Is there a library that can do that?

For instance, instead of

string.Format("string1={0}, string2={1}", v1, v2)

something like

string.Format("string1={*}, string2={*}", v1, v2)

假设你使用的是.NET 3.5或更高版本，你可以通过编写自己的字符串扩展和params关键字来完成。

编辑：无聊，代码是草率和容易出错的，但把这个类放在你的项目中，并在必要时使用它的命名空间：

public static class StringExtensions { public static string FormatEx(this string s, params string[] parameters) { Regex r = new Regex(Regex.Escape("{*}")); for (int i = 0; i < parameters.Length; i++) { s = r.Replace(s, parameters[i], 1); } return s; } }

用法：

Console.WriteLine("great new {*} function {*}".FormatEx("one", "two"));

You could accomplish this yourself by writing your own string extension coupled with the params keyword, assuming you're using .NET 3.5 or higher.

Edit: Got bored, the code is sloppy and error prone, but put this class in your project and using its namespace if necessary:

public static class StringExtensions { public static string FormatEx(this string s, params string[] parameters) { Regex r = new Regex(Regex.Escape("{*}")); for (int i = 0; i < parameters.Length; i++) { s = r.Replace(s, parameters[i], 1); } return s; } }

Usage:

Console.WriteLine("great new {*} function {*}".FormatEx("one", "two"));在.net中替代string.Format（“... {0} ... {1} ...”，v1，v2）(alternatives to string.Format(“… {0}…{1}…”,v1,v2) in .net?)
