String Class Methods and Fields
There are lot of methods and fields which are supported by string class in .Net. In this article we discuss about all those methods and fields.
string str1 = "string 1";
string str2 = "string 2";
Empty - Public static field representing the empty string.
E.g: String str1 = String.Empty;
Compare() - Overloaded public static method that compares two strings.
E.g:
int i = str1.CompareTo(str2);
CompareOrdinal() - Overloaded public static method that compares two strings without regard to local or culture.
Concat() - Overloaded public static method that creates a new string from one or more strings.
E.g:
string str3 = string.Concat(str1, str2);
Copy() - Overloaded public static method that creates a new string by copying another.
E.g:
string str3 = string.Copy(str1);
Equals() - Overloaded public static method that determines if two strings have the same value.
E.g:
bool bEqual = str1.Equals(str2);
Format() - Overloaded public static method that formats a string using a format specification.
Intern() - Overloaded public static method that returns a reference to the specified instance of a string.
IsInterned() - Overloaded public static method that returns a reference for the string.
Join() - Overloaded public static method that concatenates a specified string between each element of a string array.
Chars() - The string indexer.
Length() - The number of characters in the instance.
Clone() - Returns the string.
Compareto() - Compares this string with another.
CopyTo() - Copies the specified number of characters to an array of Unicode characters.
EndsWith() - Indicates whether the specified string matches the end of this string.
E.g:
bool bVal = str1.EndsWith("str");
Equals() - Determines if two strings have the same value.
Insert() - Returns a new string with the specified string inserted.
E.g:
string str3 = str1.Insert(str1.IndexOf("str"), str2);
LastIndexOf() - Reports the index of the last occurrence of a specified character or string within the string.
PadLeft() - Right-aligns the characters in the string, padding to the left with spaces or a specified character.
PadRight() - Left-aligns the characters in the string, padding to the right with spaces or a specified character.
Remove() - Deletes the specified number of characters.
Split() - Returns the substrings delimited by the specified characters in a string array.
StartsWith() - Indicates if the string starts with the specified characters.
E.g:
bool bVal = str1.StartsWith("str");
SubString() - Retrieves a substring.
ToCharArray() - Copies the characters from the string to a character array.
ToLower() - Returns a copy of the string in lowercase.
ToUpper() - Returns a copy of the string in uppercase.
Trim() - Removes all occurrences of a set of specified characters from beginning and end of the string.
TrimEnd() - Behaves like Trim, but only at the end.
