C# Access Strings
Access Strings
You can access the characters in a string by referring to its index number
inside square brackets []
.
This example prints the first character in myString:
Note: String indexes start with 0: [0] is the first character. [1] is the second character, etc.
This example prints the second character (1) in myString:
You can also find the index position of a specific character in a string, by using the IndexOf()
method:
Example
string myString = "Hello";
Console.WriteLine(myString.IndexOf("e")); // Outputs "1"
Another useful method is Substring()
, which extracts the characters from a string,
starting from the specified character position/index, and returns a new string. This method is often used together with IndexOf()
to get the specific character position:
Example
// Full name
string name = "John Doe";
// Location of the letter D
int charPos = name.IndexOf("D");
// Get last name
string lastName = name.Substring(charPos);
// Print the result
Console.WriteLine(lastName);
