Chapter 3: Pulling Strings

In This Chapter

Pulling and twisting a string with C# — just don’t string me along

Matching similar values

Doing other string operations, such as searching, trimming, splitting, and concatenating

Parsing strings read into the program

Formatting output strings manually or using the String.Format() method

For many applications, you can treat a string like one of the built-in value-type variable types such as int or char. Certain operations that are otherwise reserved for these intrinsic types are available to strings:

int i = 1;          // Declare and initialize an int.

string s = “abc”;   // Declare and initialize a string.

string s1 = new String();

string s2 = “abcd”;

int lengthOfString = s2.Length;
