This method calculates the average of the object's elements.This article describes several ways to convert from System::String* to char* by using managed extensions in Visual C++. This property returns the number of elements in the object. Throw gcnew InvalidOperationException( " Index out of range." ) Get, set, and add values with this indexer property. Add additional values with this method. Construct the object and add an initial list of values.ĭata = gcnew ArrayList( (Array^)values ) ĭefaultProvider = gcnew AverageInfo( AverageType::ArithmeticMean ) arithmetic mean, geometric mean, or median. return an average of the array elements in one of three types: This class encapsulates an array of double values and implements Use this property to set or get the type of averaging. Virtual Object^ GetFormat( Type^ argType ) if an object of AverageInfo type is requested. This method returns a reference to the containing object Specify the type of averaging in the constructor. Ref class AverageInfo: public IFormatProvider The class instance determines the type of Pass an instance of this class to methods that require an Define the types of averaging available in the class This method returns a character whose Unicode value is the average of the array of Double values, using the object that implements IFormatProvider to determine how to calculate the average. An object of each class is passed to the ToChar method. Objects of the class that implements IConvertible hold an array of Double values. The following example defines a class that implements IConvertible and a class that implements IFormatProvider. If value is not null, this method wraps a call to the IConvertible.ToChar implementation of the underlying type of value. ' Cannot convert a null reference to a Char. ' Conversion of the Decimal value 175.6 to a Char is not supported. ' Conversion of the Double value 169.34 to a Char is not supported. ' The SByte value -17 is outside the range of the Char data type. ' Conversion of the DateTime value 12:00:00 AM to a Char is not supported. ' The Int32 value 335812911 is outside the range of the Char data type. ' The Int32 value 109324 is outside the range of the Char data type. ' String must be exactly one character long. ' The example displays the following output: object values = is outside the range of the Char data type.", _Ĭonsole.WriteLine("Cannot convert a null reference to a Char.") The following example attempts to convert each element in an object array to a Char value. Value is less than Char.MinValue or greater than Char.MaxValue. Returns the specified Unicode character value no actual conversion is performed.Ĭonverts the value of the specified 8-bit unsigned integer to its equivalent Unicode character.Ĭonverts the value of the specified 32-bit signed integer to its equivalent Unicode character. Overloads ToChar(Object)Ĭonverts the value of the specified object to a Unicode character.Ĭonverts the value of the specified object to its equivalent Unicode character, using the specified culture-specific formatting information.Ĭonverts the value of the specified 64-bit unsigned integer to its equivalent Unicode character.Ĭonverts the value of the specified 32-bit unsigned integer to its equivalent Unicode character.Ĭonverts the value of the specified 16-bit unsigned integer to its equivalent Unicode character.Ĭonverts the first character of a specified string to a Unicode character.Ĭalling this method always throws InvalidCastException.Ĭonverts the value of the specified 8-bit signed integer to its equivalent Unicode character.Ĭonverts the first character of a specified string to a Unicode character, using specified culture-specific formatting information.Ĭonverts the value of the specified 64-bit signed integer to its equivalent Unicode character.Ĭonverts the value of the specified 16-bit signed integer to its equivalent Unicode character. Converts a specified value to a Unicode character.
