ValueOf(Int32)
Returns an Integer instance representing the specified
int value.
[Android.Runtime.Register("valueOf", "(I)Ljava/lang/Integer;", "")]
public static Java.Lang.Integer ValueOf (int i);[<Android.Runtime.Register("valueOf", "(I)Ljava/lang/Integer;", "")>]
static member ValueOf : int -> Java.Lang.IntegerParameters
- i
- Int32
an int value.
Returns
an Integer instance representing i.
- Attributes
Remarks
Returns an Integer instance representing the specified int value. If a new Integer instance is not required, this method should generally be used in preference to the constructor #Integer(int), as this method is likely to yield significantly better space and time performance by caching frequently requested values.
This method will always cache values in the range -128 to 127, inclusive, and may cache other values outside of this range.

Applies to
ValueOf(String)
Returns an Integer object holding the
value of the specified String.
[Android.Runtime.Register("valueOf", "(Ljava/lang/String;)Ljava/lang/Integer;", "")]
public static Java.Lang.Integer ValueOf (string s);[<Android.Runtime.Register("valueOf", "(Ljava/lang/String;)Ljava/lang/Integer;", "")>]
static member ValueOf : string -> Java.Lang.IntegerParameters
- s
- String
the string to be parsed.
Returns
an Integer object holding the value
represented by the string argument.
- Attributes
Exceptions
if string cannot be parsed as an integer value.
Remarks
Returns an Integer object holding the value of the specified String. The argument is interpreted as representing a signed decimal integer, exactly as if the argument were given to the #parseInt(java.lang.String) method. The result is an Integer object that represents the integer value specified by the string.
In other words, this method returns an Integer object equal to the value of:
<blockquote> new Integer(Integer.parseInt(s))</blockquote>

Applies to
ValueOf(String, Int32)
Returns an Integer object holding the value
extracted from the specified String when parsed
with the radix given by the second argument.
[Android.Runtime.Register("valueOf", "(Ljava/lang/String;I)Ljava/lang/Integer;", "")]
public static Java.Lang.Integer ValueOf (string s, int radix);[<Android.Runtime.Register("valueOf", "(Ljava/lang/String;I)Ljava/lang/Integer;", "")>]
static member ValueOf : string * int -> Java.Lang.IntegerParameters
- s
- String
the string to be parsed.
- radix
- Int32
the radix to be used in interpreting s
Returns
an Integer object holding the value
represented by the string argument in the specified
radix.
- Attributes
Exceptions
if string cannot be parsed as an integer value, or
radix Character.MAX_RADIX.
Remarks
Returns an Integer object holding the value extracted from the specified String when parsed with the radix given by the second argument. The first argument is interpreted as representing a signed integer in the radix specified by the second argument, exactly as if the arguments were given to the #parseInt(java.lang.String, int) method. The result is an Integer object that represents the integer value specified by the string.
In other words, this method returns an Integer object equal to the value of:
<blockquote> new Integer(Integer.parseInt(s, radix))</blockquote>
