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?

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 |
stringArray.ToList().Contains(stringToCheck)
其他回答
方法如下:
using System.Linq;
if(stringArray.Any(stringToCheck.Contains))
/* or a bit longer: (stringArray.Any(s => stringToCheck.Contains(s))) */
这个函数检查stringToCheck是否包含stringArray的子字符串。如果你想确保它包含所有的子字符串,将Any更改为all:
if(stringArray.All(stringToCheck.Contains))
要完成前面的回答,对于IgnoreCase检查,使用:
stringArray.Any(s => stringToCheck.IndexOf(s, StringComparison.CurrentCultureIgnoreCase) > -1)
你可以这样做:
string stringToCheck = "text1";
string[] stringArray = { "text1", "testtest", "test1test2", "test2text1" };
foreach (string x in stringArray)
{
if (stringToCheck.Contains(x))
{
// Process...
}
}
也许你正在寻找一个更好的解决方案……参考Anton Gogolev使用LINQ的答案。

只需使用LINQ方法:
stringArray.Contains(stringToCheck)
试试这个。没有任何循环的需要。
string stringToCheck = "text1";
List<string> stringList = new List<string>() { "text1", "someothertext", "etc.." };
if (stringList.Exists(o => stringToCheck.Contains(o)))
{
}
