Summary of. NET Web Development

Creating controls in an ASPX file in the lower-right corner with control information sort by class will sort the control information installation class

Clicking on the control increases the paging [events] page of the property page to increase its event function

string manipulation and its time operations

Fn_name. Insert (0, "large"). The ToString () string is input from "0123" starting at 0, and input 0 is displayed at the front of the character 1 is displayed after 1
Variable. Insert (int,sring). ToString (); Increment the specified position string
Variable. Remove (Int,int). ToString (); Delete the specified position string
Variable. Replace (string1,string2);//replace string String2 replacement string1
Variable. Substring (int,int);//intercept a string to intercept several characters from a character
* * Date String Interception * * Chapter 4
Intercept string to intercept generated date variable string
DateTime class to get time requires a real column DateTime class
DateTime time = new DateTime (2006,5,20); Real-column and initialize

DateTime DDate1 = time. AddDays (int)//AddDays action can modify the number of days based on the date that is actually obtained
(-int)//Increase int decrease-int
DateTime DDate2 = ddate1.addmonths (23)//modified month on the basis of its DDate1 date
(-23)//Increase int decrease-int
AddYears year

DateTime.Now Get the current date
CompareTo is a date comparison such as:
Ddate1.compareto (DateTime.Now) Comparison of the date and the current date
int now_h = DateTime.Now.Hour; Get Current Hour
Ddate1.dayofweek = Output Week
Response.Write ("<br/>"), can have HTML code but note that Response is displayed on the page text can use HTML text code.

Two bars
* * Type Conversion * * Date type formatted output and type string split

Tip: Response.Write ();//Escape + can connect string

A: First introduce. NET several basic types
BYTE 8-bit unsigned integer type: 1 bytes
Short 16-bit signed integer type: 2-byte short integer type
int 32-bit signed integer type: 4 byte integer type
Long 64-bit signed Long integer type: 8 bytes
Float single-precision floating-point number
Double dual-precision floating-point number
Two: type conversion
Double-int
Double num = 3.1415926;
int number = (int) num;//Display type conversion Universal

string int
String sql = num. ToString (); Universal Time Type (DateTime) can also be converted

String->string[] or char[]

String sql = "Zhao Yun";
char[] path = SQL. Tochararry (); Note that the ToCharArray is an array type that array is a C # array type

Split String * * *
String se = "big luck Everyone";
string[] sq = se. Split (' big '); Assigning a large character split in an SE string to an stirng array

Date formatted as Short date (date formatted output type)

such as: Datatiem B = new Datetiem (2006,3,23,23,13,56);
Month and day time
Response.Write (B.tostring ("D") + "<br/>");//To Tostirng ("D");//The date format shown is:
2006.3.23 Thursday show year-month-day week

Output format: b.tostring ("D"); = year-month-day week
B.tostring ("dddd HH:mm:ss"); = Week: minute: seconds dddd Week hh mm min SS sec
B.tostring ("yyyy mm DD day") = year-month Day
Three-Bar * * * Process Control
Random number generator The class and the date class need to be real-listed to use
Random rnd = new Random ();
int a = rnd. Next (10); Next function is to return less than the specified maximum worth of non-negative
Switch Case:default:break;
If else if else
For
Do While
While
While
String kstr = "";
Kstr.padleft (N, ' * ').  Tostirng (); The PadLeft returns a new string n that represents the string length, ' * ' for the new value
Kstr.length: Get string length

Convert a string to a time type
DateTime D = DateTime.Parse (String);
