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
一个不需要任何LINQ的简单解决方案:
String.Join(",", array).Contains(Value + ",");
其他回答
使用Array类的Find或FindIndex方法:
if(Array.Find(stringArray, stringToCheck.Contains) != null)
{
}
if(Array.FindIndex(stringArray, stringToCheck.Contains) != -1)
{
}

我在控制台应用程序中使用以下命令检查参数
var sendmail = args.Any( o => o.ToLower() == "/sendmail=true");
LINQ:
arrray。Any(x => word.Equals(x));
这是为了查看数组是否包含单词(精确匹配)。使用. contains作为子字符串，或者其他任何你可能需要应用的逻辑。
试试这个。示例:检查字段是否包含数组中的任何单词。检查字段(someField)是否包含数组中的任何单词。
String[] val = { "helloword1", "orange", "grape", "pear" };
Expression<Func<Item, bool>> someFieldFilter = i => true;
someFieldFilter = i => val.Any(s => i.someField.Contains(s));

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