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
也许是这样的:
string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };
if (Array.Exists<string>(stringArray, (Predicate<string>)delegate(string s) {
return stringToCheck.IndexOf(s, StringComparison.OrdinalIgnoreCase) > -1; })) {
Console.WriteLine("Found!");
}

⚠️ Note: this does not answer the question asked |

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 |
string strName = "vernie";
string[] strNamesArray = { "roger", "vernie", "joel" };
if (strNamesArray.Any(x => x == strName))
{
// do some action here if true...
}
使用Array类的Find或FindIndex方法:
if(Array.Find(stringArray, stringToCheck.Contains) != null)
{
}
if(Array.FindIndex(stringArray, stringToCheck.Contains) != -1)
{
}
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));

最简单最简单的方法:
bool bol = Array.Exists(stringarray, E => E == stringtocheck);
一个不需要任何LINQ的简单解决方案:
String.Join(",", array).Contains(Value + ",");
