Study Notes
String Operations
-
str.Substring(0, 5)returns a substring from the start of the string up to the 5th character. -
str.Substring(6)returns a substring from the 6th character to the end of the string. - String interpolation involves substituting a value into a string, e.g.,
$"My full name is: {firstName} {lastName}". -
IndexOf("F")returns the position of the character "F" in the string. -
Remove(1, this.Name.Length-1)removes all characters from the 2nd position to the end of the string, leaving only the 1st character. -
Replace("F", "test")replaces all occurrences of "F" with "test" in the string, resulting in "torm1".
String Properties and Methods
-
Lengthproperty is used to determine the length of a string. -
String.Joinmethod is used to concatenate strings to form another string. -
Substringmethod has two overloaded forms:Substring(Int32)andSubstring(Int32, Int32). -
Substring(Int32)method retrieves a substring from the specified position to the end of the string.
Arrays and Data Structures
- An array is a collection of data attached to a variable.
- A multi-dimensional array is an array of arrays that stores homogeneous data in tabular form.
- A listview displays a collection of items that can be displayed using one of four different views, and it can be represented in a tabular form.
User Interface and Events
- A listbox is a control that enables users to select items from a list by clicking.
- A button click event can be used to populate a listbox, e.g., when the button is clicked, the item is inserted into the listbox.
- The
Button1_Click()event is generated by the code editor at design time and can be used to put data into the listbox when the user presses enter.
