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
public bool ContainAnyOf(string word, string[] array)
{
for (int i = 0; i < array.Length; i++)
{
if (word.Contains(array[i]))
{
return true;
}
}
return false;
}
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";
}
}
}
要完成前面的回答,对于IgnoreCase检查,使用:
stringArray.Any(s => stringToCheck.IndexOf(s, StringComparison.CurrentCultureIgnoreCase) > -1)
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));
演示了三个选项。我认为第三条是最简洁的。
