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?

| 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...
}
其他回答
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。
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));
public bool ContainAnyOf(string word, string[] array)
{
for (int i = 0; i < array.Length; i++)
{
if (word.Contains(array[i]))
{
return true;
}
}
return false;
}
你也可以像Anton Gogolev建议的那样，检查stringArray1中的任何项是否与stringArray2中的任何项匹配:
using System.Linq;
if(stringArray1.Any(stringArray2.Contains))
同样，stringArray1中的所有项都匹配stringArray2中的所有项:
using System.Linq;
if(stringArray1.All(stringArray2.Contains))
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。
