Chapter 2: Summary

Even for experienced programmers, C# introduces several new programming constructs. For example, as part of the section on data types, this chapter covered the type decimal, which can be used to perform financial calculations without floating-point anomalies. In addition, the chapter introduced the fact that the Boolean type, bool, does not convert implicitly to or from the integer type, thereby preventing the mistaken use of the assignment operator in a conditional expression. Other characteristics of C# that distinguish it from many of its predecessors are the @ verbatim string qualifier and raw string literals (both force a string to ignore the escape character); string interpolation, which makes code easier to read by embedding it into the string; and the immutable nature of the string data type.

In Chapter 3, we continue the topic of data types by elaborating more on the two types of data types: value types and reference types. In addition, we look at combining data elements together into tuples and arrays.
