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?

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");

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");
方法如下:
using System.Linq;
if(stringArray.Any(stringToCheck.Contains))
/* or a bit longer: (stringArray.Any(s => stringToCheck.Contains(s))) */
这个函数检查stringToCheck是否包含stringArray的子字符串。如果你想确保它包含所有的子字符串，将Any更改为all:
if(stringArray.All(stringToCheck.Contains))
一个不需要任何LINQ的简单解决方案:
String.Join(",", array).Contains(Value + ",");
您也可以尝试这个解决方案。
string[] nonSupportedExt = { ".3gp", ".avi", ".opus", ".wma", ".wav", ".m4a", ".ac3", ".aac", ".aiff" };
bool valid = Array.Exists(nonSupportedExt,E => E == ".Aac".ToLower());
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";
}
}
}
