使用c＃

Question

我有一个包含字符串值的列表arrString。我需要在C＃中使用for循环检查字符串lookupvalue.Longname是否存在于列表中。

 for(int i = 0 ;i < ResoCustomFields.LongnameNotToBeTaken.Count ;i++)
 {
    string myStringList = ResoCustomFields.LongnameNotToBeTaken[i].ToString();
    var arrString = myStringList.Trim('(',')').Split(',').ToList();
    if(arrString.Contains(resoField))
    {
    // if(!arrString[i].Any(str=>str.ToString().Contains(lookupValue.LongName)))
    // if(lookupValue.LongName.Contains(arrString.ToString()))
    //(!arrString.Any(str => str.Equals(lookupValue.LongName)))
    // if(!arrString.Equals(lookupValue.LongName))                                                      
    {
    }
}

您可以尝试以下代码：

int pos = Array.IndexOf(arrString, lookupValue.LongName);
if (pos > -1)
{
//// DO YOUR STUF
}
