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 |
最简单最简单的方法:
bool bol = Array.Exists(stringarray, E => E == stringtocheck);

我使用下面的代码来检查字符串是否包含字符串数组中的任何项:
foreach (string s in stringArray)
{
if (s != "")
{
if (stringToCheck.Contains(s))
{
Text = "matched";
}
}
}

stringArray.ToList().Contains(stringToCheck)
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。
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))
int result = Array.BinarySearch(list.ToArray(), typedString, StringComparer.OrdinalIgnoreCase);
