我该怎么办的sscanf在c＃ [英] how do I do sscanf in c#

问题描述

我如何在C＃中做到这一点。

how do I do this in C#?

int a,b,c;
sscanf(astring,"%d %d %d",&a,&b,&c);

最少的代码和相关性最好，是有一些内置的正则表达式的东西？

minimal code and dependencies is preferable, is there some built in regex stuff?

我使用C＃4.0

推荐答案

如果像scannf你愿意假设用户。将给出完全正确的数据，那么你可以做以下

If like scannf you are willing to assume that users will give completely correct data then you can do the following.

string astring = ...;
string[] values = astring.Split(new char[] {' '}, StringSplitOptions.RemoveEmptyEntries);
int a = Int32.Parse(values[0]);
int b = Int32.Parse(values[1]);
int c = Int32.Parse(values[2]);

正则表达式将工作对于这种情况，但他们都有点矫枉过正。该字符串可以很容易地与上述拆分方法标记化。

Regular expressions would work for this scenario but they are a bit overkill. The string can easily be tokenized with the aforementioned Split method.
