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
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) {
// ....
}
其他回答
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";
}
}
}
也许是这样的:
string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };
if (Array.Exists<string>(stringArray, (Predicate<string>)delegate(string s) {
return stringToCheck.IndexOf(s, StringComparison.OrdinalIgnoreCase) > -1; })) {
Console.WriteLine("Found!");
}

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)

string strName = "vernie";
string[] strNamesArray = { "roger", "vernie", "joel" };
if (strNamesArray.Any(x => x == strName))
{
// do some action here if true...
}
试试这个。没有任何循环的需要。
string stringToCheck = "text1";
List<string> stringList = new List<string>() { "text1", "someothertext", "etc.." };
if (stringList.Exists(o => stringToCheck.Contains(o)))
{
}
