For example, there is a sentence template:
"Tell me the forcast of @city"
And the sentence:
"Tell me the forcast of New York"
How I can get the city name (New York) using the template? Or, for example:
"Tell me the forcast of @city for @date" -> "Tell me the forcast of Las Vegas for tomorrow"
How I can get Las Vegas and tomorrow?

Please clarify: is it always the case that the string you are parsing for the 'City is always going to have the sequence "Tell me the forecast of;" or, is it the case that you also want to handle parsing other sentences like: "I was looking at the forecast for Los Angeles." By the way, "forcast" is spelled "forecast."

Sorry, I am not an english-speaking guy.
I have a list of sentences, from whici i will get the most appropriate sentence.
For example: "Tell me the forecast of @city", "Tell me the forecast of @city for @date", "What is the weather in @city" etc.

Basically you can replace the keyword @city with \s+(?<city>[\S\s]+?)\s+

Example:

C#

string template1 = @"^Tell me the forcast of\s+(?<city>[\S\s]+?)\s+for\s+(?<date>[\S\s]+)$";

In C# you use

C#

Match m = Regex.Match("Tell me the forcast of Las Vegas for tomorrow", template1);
if (m.Success)
{
    string city = m.Groups["city"].Value;
    string date = m.Groups["date"].Value;
}

The rest you can do by yourself.
