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
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));
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。
使用Array类的Find或FindIndex方法:
if(Array.Find(stringArray, stringToCheck.Contains) != null)
{
}
if(Array.FindIndex(stringArray, stringToCheck.Contains) != -1)
{
}

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);
我使用了类似于Maitrey684的IndexOf方法和Theomax的foreach循环来创建它。(注意:前3个“字符串”行只是一个例子,你可以创建一个数组,并把它变成适当的格式)。
如果您想比较两个数组,它们将以分号分隔,但最后一个值后面不会有分号。如果你在数组的字符串形式中添加了一个分号(即a;b;c变成了a;b;c;),你可以使用"x;"进行匹配,无论它在什么位置:
bool found = false;
string someString = "a-b-c";
string[] arrString = someString.Split('-');
string myStringArray = arrString.ToString() + ";";
foreach (string s in otherArray)
{
if (myStringArray.IndexOf(s + ";") != -1) {
found = true;
break;
}
}
if (found == true) {
// ....
}

string strName = "vernie";
string[] strNamesArray = { "roger", "vernie", "joel" };
if (strNamesArray.Any(x => x == strName))
{
// do some action here if true...
