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
使用Array类的Find或FindIndex方法:
if(Array.Find(stringArray, stringToCheck.Contains) != null)
{
}
if(Array.FindIndex(stringArray, stringToCheck.Contains) != -1)
{
}
其他回答
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) {
// ....
}

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 |
只需使用LINQ方法:
stringArray.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;
}
string [] lines = {"text1", "text2", "etc"};
bool bFound = lines.Any(x => x == "Your string to be searched");
如果搜索的字符串与数组'lines'中的任何元素匹配,则bFound设置为true。

试试这个:
不需要使用LINQ
if (Array.IndexOf(array, Value) >= 0)
{
//Your stuff goes here
}
