[Serializable] |
Int32 provides methods to compare instances of this type, convert the value of an instance to its String representation, and convert the String representation of a number to an instance of this type.
For information about how format specification codes control the String representation of value types, see the conceptual topic at MSDN: formattingoverview.
This type implements interfaces IComparable, IFormattable, and IConvertible. Use the Convert class for conversions instead of this type's explicit interface member implementation of IConvertible.| MaxValue | Represents the largest possible value of an Int32. This field is constant. |
| MinValue | Represents the smallest possible value of Int32. This field is constant. |
| CompareTo | Compares this instance to a specified object and returns an indication of their relative values. |
| Equals | Overridden: Returns a value indicating whether this instance is equal to a specified object. |
| GetHashCode | Overridden: Returns the hash code for this instance. |
| GetType (inherited from System.Object) |
See base class member description: System.Object.GetType Derived from System.Object, the primary base class for all objects. |
| GetTypeCode | Returns the TypeCode for value type Int32. |
| Parse | Overloaded:Parse(string s) Converts the string representation of a number to its 32-bit signed integer equivalent. |
| Parse | Overloaded:Parse(string s, IFormatProvider provider) Converts the string representation of a number in a specified culture-specific format to its 32-bit signed integer equivalent. |
| Parse | Overloaded:Parse(string s, NumberStyles style) Converts the string representation of a number in a specified style to its 32-bit signed integer equivalent. |
| Parse | Overloaded:Parse(string s, NumberStyles style, IFormatProvider provider) Converts the string representation of a number in a specified style and culture-specific format to its 32-bit signed integer equivalent. |
| ToString | Overloaded:ToString()Overridden: Converts the numeric value of this instance to its equivalent string representation. |
| ToString | Overloaded:ToString(IFormatProvider provider) Converts the numeric value of this instance to its equivalent string representation using the specified culture-specific format information. |
| ToString | Overloaded:ToString(string format) Converts the numeric value of this instance to its equivalent string representation, using the specified format. |
| ToString | Overloaded:ToString(string format, IFormatProvider provider) Converts the numeric value of this instance to its equivalent string representation using the specified format and culture-specific format information. |

s
| Exception Type | Condition |
|---|---|
| ArgumentNullException | s is null. |
| FormatException | s does not consist solely of an optional negative sign followed by a sequence of digits ranging from 0 to 9. |
| OverflowException | s represents a number less than Int32.MinValue or greater than Int32.MaxValue. |
[ws][sign]digits[ws]
Items in square brackets ([ and ]) are optional; and the values of the other items are as follows.
The s parameter is parsed using the formatting information in a NumberFormatInfo initialized for the current system culture. For more information, see NumberFormatInfo.CurrentInfo.

Items in square brackets ([ and ]) are optional; and the values of the other items are as follows.
The provider parameter is an IFormatProvider that obtains a NumberFormatInfo object. The NumberFormatInfo provides culture-specific information about the format of s. If provider is null, the NumberFormatInfo for the current culture is used.

| Exception Type | Condition |
|---|---|
| ArgumentNullException | s is null. |
| ArgumentException | style is not a valid combination of bit flags from the NumberStyles enumeration. |

| OverflowException | s represents a number less than Int32.MinValue or greater than Int32.MaxValue. |
[ws][sign]digits[ws]
Items in square brackets ([ and ]) are optional; and the values of the other items are as follows.
The style parameter can be one or more NumberStyles enumerated constants combined using a bitwise OR operation (except NumberStyles.Any and NumberStyles.AllowDecimalPoint, which are invalid for the type returned by this method).
