问题 I need to compare strings for a search mechanism on a web site. I use C#. I tried two ways: consultants.Where(x => x.Description.ToLower().Contains(vm.Description.ToLower())); and consultants.Where(x => Regex.IsMatch(x.Description, vm.Description, RegexOptions.IgnoreCase)); Both work fine for all English characters. So if I search for, say, "english", that's no problem. But as soon as I try searching for a string that contains non-English characters, it doesn't work. For example, if I try

问题 What is the correct way to compare two strings say abc and bcd depending on the alphabetic order? Is there a built in command to do so? Or would > or .lt. do the work without any problems? 回答1: The intrinsic relational operators .lt. and < (along with the "equal" and "greater than" friends) indeed may be used to compare character variables. We see the definition (Fortran 2018, 10.1.5.5.1): the character operand x1 is considered to be less than x2 if the character value of x1 at this position

问题 I was just debugging a script and found that an if-statement wasn't working the way I expected it to. var_dump("6064365413078728979" == "6064365413078728452"); die(); The code above will result in the following: bool(true) With the === operator it works as expected. Anyone got any ideas why? I'm using PHP Version 5.3.13 with a wamp installation on a x64 windows machine. 回答1: <?php $a=6064365413078728979; $b=6064365413078728452; echo $a."<br>".$b; //var_dump( $a==$b ); die(); ?> When you run

问题 Since some days I try to find a way to subset my data frame by comparing a character in a column with a string in another column. In case the character is not within the string, I want to copy a value to a new column.
