在c#中找到完全匹配 [英] Find exact match in c#
问题描述
我试图开发这个包含字符串(ing)和字符串数组(splitwords)的代码。
我需要运行一个字符串,如果它匹配字符串数组中的字符串做某事使用原始字符串。
Im trying to develop this code that haves a string(ing) and a string array (splitwords).
I need to run a string and if it matches the string from the string array does something with that original string.
StringBuilder builder = new StringBuilder();
ing = " " + ing + " ";
builder.Append(@"{\rtf1\ansi");
foreach (string word in splitwords)
{
if (Regex.IsMatch(ing, @"(?<![\w])" + word + @"(?![\w])"))
{
// for example put the word in UPPERCASE
}
builder.Append(ing);
builder.Append(@"}");
return builder.ToString();
全部它运行的测试没问题,但是如果我有,那么
文字(ing):我有一个带鸡蛋的收据,但其他只有一个鸡蛋;
单词(分词):蛋,蛋,有收据
结果我得到使用上面的代码:我收到EGG的收据,但其他只有一个EGG
我需要的是:我收到了EGGS的收据,但其他人收到了只需一个EGG
如何更改我的if条件来解决这个问题?
With all the tests it runs ok, but if if I have
Text(ing): "I have a receipt with eggs but others with just one egg";
Words(splitwords): "egg","eggs", "have a receipt"
Result I get with the code above: "I HAVE A RECEIPT with EGG s but others with just one EGG"
What I need : "I HAVE A RECEIPT with EGGS but others with just one EGG"
How can I change my if condition to solve this problem?
推荐答案
示例代码:
sample code:
var splitwords =new string[] {"egg","eggs", "have a receipt"};
string input ="I have a receipt with eggs but others with just one egg";
foreach (string word in splitwords)
{
var regex = new Regex(@"(?<![\w])" + word + @"(?![\w])", RegexOptions.IgnoreCase);
input = regex.Replace(input, m=>m.ToString().ToUpper());
}
//inpt = "I HAVE A RECEIPT with EGGS but others with just one EGG"
只替换正则表达式的匹配项,那么它应该可以正常工作。
replace only the matching items of regex then it should work fine.
