AnyValueMap

Cross-language implementation of a dynamic map (dictionary) object that can hold values of any type. It also provides several methods to convert the stored values to different types.

Inherits: ICloneable, Dictionary<string, object>

Description

The AnyValueMap class provides a cross-language implementation of a dynamic map (dictionary) object that can hold values of any type. In addition, it provides several methods to convert the stored values to different types, such as bool, integer or datetime.

  • tuples: object[] - list of values where odd elements are keys and the following even elements are values.
  • returns: AnyValueMap - newly created AnyValueArray.

FromTuplesArray

Creates a new AnyValueMap from a list of key-value pairs called tuples. The method is similar to fromTuples but tuples are passed as an array instead of parameters.

public static AnyValueMap FromTuplesArray(params object[] tuples)

  • tuples: object[] - list of values where odd elements are keys and the following even elements are values.
  • returns: AnyValueMap - newly created AnyValueArray.

  • value: object - value to be converted
  • returns: AnyValueMap - newly created AnyValueMap.

Examples

var value1 = new AnyValueMap(new Dictionary<string, object>{
    {"key1", 1},

    });

value1.GetAsBoolean("key1");   // Result: true
value1.GetAsInteger("key2");   // Result: 123
value1.GetAsFloat("key2");     // Result: 123.456
value1.GetAsDateTime("key3");  // Result: new DateTime(2018,0,1)
