ConvertTo(Object, Type)
Converts valueToConvert to resultType
public:
static System::Object ^ ConvertTo(System::Object ^ valueToConvert, Type ^ resultType);
public:
static Platform::Object ^ ConvertTo(Platform::Object ^ valueToConvert, Platform::Type ^ resultType);
public static object ConvertTo (object valueToConvert, Type resultType);
static member ConvertTo : obj * Type -> obj
Public Shared Function ConvertTo (valueToConvert As Object, resultType As Type) As Object
Parameters
- valueToConvert
- Object
value to be converted and returned
- resultType
- Type
type to convert valueToConvert
Returns
converted value
Exceptions
if resultType is null
if the conversion failed
Remarks
A null valueToConvert can be converted to :
string - returns ""
char - returns '\0'
numeric types - returns 0 converted to the appropriate type
boolean - returns LanguagePrimitives.IsTrue(null)
PSObject - returns new PSObject())
array - returns an array with null in array[0]
non value types - returns null
The following conversions are considered language standard and cannot be customized:
- from derived to base class - returns valueToConvert intact
- to PSObject - returns PSObject.AsPSObject(valueToConvert)
- to void - returns AutomationNull.Value
- from array/IEnumerable to array - tries to convert array/IEnumerable elements
- from object of type X to array of X - returns an array with object as its only element
- to bool - returns LanguagePrimitives.IsTrue(valueToConvert)
- to string - returns a string representation of the object.
In the particular case of a number to string,
the conversion is culture invariant.
- from IDictionary to Hashtable - uses the Hashtable constructor
- to XmlDocument - creates a new XmlDocument with the
string representation of valueToConvert
- from string to char[] - returns ((string)valueToConvert).ToCharArray()
- from string to RegEx - creates a new RegEx with the string
- from string to Type - looks up the type in the minishell's assemblies
- from empty string to numeric - returns 0 converted to the appropriate type
- from string to numeric - returns a culture invariant conversion
- from ScriptBlock to Delegate - returns a delegate wrapping that scriptblock.
- from Integer to Enumeration - Uses Enum.ToObject
- to WMI - Instantiate a WMI instance using
System.Management.ManagementObject
- to WMISearcher - returns objects from running WQL query with the
string representation of valueToConvert. The
query is run using ManagementObjectSearcher Class.
- to WMIClass - returns ManagementClass represented by the
string representation of valueToConvert.
- to ADSI - returns DirectoryEntry represented by the
string representation of valueToConvert.
- to ADSISearcher - return DirectorySearcher representd by the
string representation of valueToConvert.
If none of the cases above is true, the following is considered in order:
TypeConverter and PSTypeConverter
the Parse methods if the valueToConvert is a string
Constructors in resultType that take one parameter with type valueToConvert.GetType()
Implicit and explicit cast operators
IConvertible
If any operation above throws an exception, this exception will be wrapped into a
PSInvalidCastException and thrown resulting in no further conversion attempt.

ConvertTo(Object, Type, IFormatProvider)
Converts valueToConvert to resultType possibly considering formatProvider
public:
static System::Object ^ ConvertTo(System::Object ^ valueToConvert, Type ^ resultType, IFormatProvider ^ formatProvider);

static member ConvertTo : obj * Type * IFormatProvider -> obj
Public Shared Function ConvertTo (valueToConvert As Object, resultType As Type, formatProvider As IFormatProvider) As Object
Parameters
