[英]C# parse string using regex - number adjacent to letter
I'm having trouble writing a correct REGEX and parsing the string in C#. 我在编写正确的REGEX并在C#中解析字符串时遇到了麻烦。 The string I get an input is:
我得到输入的字符串是:
{EnemyMove X:7 Y:8} {EnemyMove X:7 Y:8}
I need to digits the follow X and the digits that follow Y, the range is 0-10. 我需要数字跟随X和跟随Y的数字,范围是0-10。 Tried the code below, but the regex is incorrect and I get an incorrect result.
尝试下面的代码,但正则表达式不正确,我得到一个不正确的结果。
I need to run it twice, once to get the digits adjacent to X and second time for the digits after Y. 我需要运行它两次,一次得到X附近的数字,第二次得到Y后的数字。
string str = "{EnemyMove X:9 Y:10}";
var regex_sp_chrs = new Regex("/X:.*?(\d+)/");
regex_sp_chrs.Matches(str );
Expected output - 9 10 预期产出 - 9 10
Thanks in advance. 提前致谢。
If you want to restrict the numbers to 0-10 range, replace \\d+
with 10|\\d
: 如果要将数字限制为0-10范围,请将
\\d+
替换为10|\\d
:
X:(?<X>10|\d)\s+Y:(?<Y>10|\d)
So, you need to remove the delimiters (leading/trailing /
) and add the Y
part. 因此,您需要删除分隔符(前导/尾随
/
)并添加Y
部分。
Group X
will contain the digits after X
and Group Y
will contain the digits after Y
. 集团
X
后,将包含数字X
和集团Y
会后包含数字Y
。
var str = "{EnemyMove X:9 Y:10}";
var regex_sp_chrs = new Regex(@"X:(?<X>10|\d)\s+Y:(?<Y>10|\d)");
var ms = regex_sp_chrs.Matches(str);
foreach (Match m in ms)
Console.WriteLine(string.Format("{0} - {1}",
m.Groups["X"].Value,
m.Groups["Y"].Value));
It will output 9 - 10
, 9
is the m.Groups["X"].Value
and 10
is the m.Groups["Y"].Value
. 它会输出
9 - 10
, 9
是m.Groups["X"].Value
和10
是m.Groups["Y"].Value
。
If you know {EnemyMove
is static (always present as a literal before X
), add it to the regex to make it safer (ie @"{EnemyMove\\s+X:(?<X>\\d+)\\s+Y:(?<Y>\\d+)"
). 如果您知道
{EnemyMove
是静态的(在X
之前始终作为文字出现),请将其添加到正则表达式以使其更安全(即@"{EnemyMove\\s+X:(?<X>\\d+)\\s+Y:(?<Y>\\d+)"
)。
