# 2.15. Converting Strings to Their Equivalent Value Type

## Problem

You have a string that represents the equivalent value of a number (”`12`“), `char` (”`a`“), `bool` (”`true`“), or a color enumeration (”`Red`“). You need to convert this string to its equivalent value type. Therefore, the number "`12`" would be converted to a numeric value such as `int`, `short`, `float`, etc. The string "`a`" would be converted to a char value '`a`', the string "`true`" would be converted to a `bool` value, and the color "`Red`" could be converted to an enumeration value (if an enumeration were defined that contained the element `Red`).

## Solution

Use the `Parse` static method of the type that the string is to be converted to. To convert a string containing a number to its numeric type, use the following code:

```// This code requires the use of the System and System.Globalization namespaces

string longString = "7654321";
int actualInt = Int32.Parse(longString);    // longString = 7654321

string dblString = "-7654.321";
double actualDbl = Double.Parse(dblString, NumberStyles.AllowDecimalPoint |
NumberStyles.AllowLeadingSign);    // longString = "-7654.321```

To convert a string containing a `Boolean` value to a `Boolean` type, use the following code:

```// This code requires the use of the System namespace

string boolString = "true";
bool actualBool = Boolean.Parse(boolString);    // actualBool = true```

To convert a string containing a `char` value to a `char` type, use the following code:

`// This code requires the use of the System namespace string charString ...`
