String Comparison

Murugesh P

Hi All,

I need to compare two strings one from data base and another generated during run time.

For Example In DB i have "The Cow is {0}"

Run time i am getting the string as "The Cow is White"

I need the result as equal. Thanks in advance.

Ah, hmm, then you are in a bit of a pickle. That is much harder.

You could try replacing any {0} (and {1}, {2}) with some RegEx and then trying to match the string you get at run time against that.

For example:

Boolean AreEqual(string template, string text)
{
string regexed = template.Replace("{0}", ".*");
regexed = template.Replace("{1}", ".*");
regexed = template.Replace("{2}", ".*");

Regex regex = new Regex(regexed);
return regex.IsMatch(text);

}

Please note, my RegEx skills are below par. And of course you would want to replace the replacements at the top with something more intelligent.

Cheers, Marjan

Hi Marjan, Thanks for your response. Basically i have to compare two strings one from Resource file another from Databse. Ex: In Resource: The cow is {0} In Data Base: The cow is {0} But during run time the Parameter {0} will be filled and it becomes "The cow is white". So comparing The cow is {0} and The cow is White will be marked as difference. And Data base will not have run time parameters. So Basically i need to compare the strings without the Parameter {0}.

String.compare(s1,s2)

If you have the value(s) of the arguments at runtime as well, then you could do something like:

Boolean Matches(string runTimeFullString, string runTimeArgument)
{
string FromDatabase = "The Cow is {0}";
return runTimeFullString.Equals(string.Format(FromDatabase, runTimeArgument));
}

If that doesn't help, could you please clarify what you are trying to achieve and what pieces of information you have to work with?

using String.Compare method.
