我想使用c#检查字符串值是否包含字符串数组中的单词。例如,
string stringToCheck = "text1text2text3";
string[] stringArray = { "text1", "someothertext", etc... };
if(stringToCheck.contains stringArray) //one of the items?
{
}
我如何检查字符串值'stringToCheck'是否包含数组中的一个词?

当前回答
int result = Array.BinarySearch(list.ToArray(), typedString, StringComparer.OrdinalIgnoreCase);
其他回答
试试这个
string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };
var t = lines.ToList().Find(c => c.Contains(stringToCheck));
它将返回您正在查找的文本的第一个出现的行。

The question asked is "how can I check if a sentence contains any word from a list of words?" |
This answer checks if a list of words contains one particular word |
只需使用LINQ方法:
stringArray.Contains(stringToCheck)
试试这个。示例:检查字段是否包含数组中的任何单词。检查字段(someField)是否包含数组中的任何单词。
String[] val = { "helloword1", "orange", "grape", "pear" };
Expression<Func<Item, bool>> someFieldFilter = i => true;
someFieldFilter = i => val.Any(s => i.someField.Contains(s));
Try:
String[] val = { "helloword1", "orange", "grape", "pear" };
String sep = "";
string stringToCheck = "word1";
bool match = String.Join(sep,val).Contains(stringToCheck);
bool anothermatch = val.Any(s => s.Contains(stringToCheck));
要完成前面的回答,对于IgnoreCase检查,使用:
stringArray.Any(s => stringToCheck.IndexOf(s, StringComparison.CurrentCultureIgnoreCase) > -1)
