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
您也可以尝试这个解决方案。
string[] nonSupportedExt = { ".3gp", ".avi", ".opus", ".wma", ".wav", ".m4a", ".ac3", ".aac", ".aiff" };
bool valid = Array.Exists(nonSupportedExt,E => E == ".Aac".ToLower());
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;
}
使用LINQ和方法组将是最快和更紧凑的方法。
var arrayA = new[] {"element1", "element2"};
var arrayB = new[] {"element2", "element3"};
if (arrayB.Any(arrayA.Contains))
return true;

| This answer checks if a list of words contains one particular word |
我会使用LINQ，但它仍然可以通过:
new[] {"text1", "text2", "etc"}.Contains(ItemToFind);
