But although they seem tricky (because of the complex grammatical rules), they are extremely useful.The truth is, a proper understanding of regular expressions can make you a smarter programmer. To fully understand the world of regular expressions, you

the Regex class includes methods such as IsMatch, Match, matches, Replace, and Split .

Freely scale your project: Builder mode, extended builder Because a complex object has many components, such as a car, a wheel, a steering wheel, an engine, and various small parts, how can we assemble these components into a car, this assembly process is long and complex. In this case, in order to hide implementation details from the outside during the construction process, you can use the

Str. Split andRegEx. Split. In my experience, it is a simple replacement of a single string, directly using a string. split ('single string'). Replace multiple strings with RegEx. split (string, @ "multiple strings ",Regexoptions. ignorecase). Here are two examples.Example 1 1 String Strsample = " 11,22, 33,44, 55,66 " ; 2 String [] Sarray = Strsample. Split ( ' , ' ); // Note: here we use single quotes instead

Key points of the builder mode: The builder mode is mainly used"Build a complex object in steps ". In this case, "step-by-step" is a stable multiplication, while all parts of complex objects change frequently. The builder mode mainly dealsFrequent demand changes for "various parts of complex objects. ItsDisadvantage:It is difficult to cope with changes in the dem

Builder mode Definition: separates the construction of a complex object from its representation so that the same build process can create different representations.The builder pattern is a step-by-step creation of a complex object that allows the user to build them only by specifying the type and content of the complex objects. The user is not aware of the specifics of the build internals. The

1, IsMatch () method, the IsMatch () method is actually a return bool worthwhile method, if the test character satisfies the regular expression return true otherwise returns false. Example: Match the regular expression, minus @ does not affect the effect of the regex r = new Regex (@ "^[0-9]");//start matching match m = R.match (This.textBox1.Text); while (m.success) { MessageBox.Show ("The first is

The arguments to the Java.lang.String.replace () method can be of type char or charsequence type (String implements the Charsequence interface)The arguments to the Java.lang.String.replaceAll (string regex, String replacement) method are the regular expression and the string to be replaced, the parameter regex if input such as "+86" or other strings with special characters will be error, need to use special

One sample is used to replace double quote from words which encapsulated by Csvwriter,You know CSV writer would take care of the double quote and comma and new line,So if the words have comma or new line, CSV writer would use the default text qualifier double quoteEnclose them, sample:Source:evan,yao CSV: "Evan,yao"And it'll replace every double quote with double quote.Such as source data is Evan,yao "CSV:" Evan,yao "" "So when we read CSV words, we should replace the additional double quote,I u
