Public Static (Shared) Methods
 CreateFromLink | Creates an Expr by reading it off a link. |
Public Static (Shared) Operators and Type Conversions
 Equality Operator | Implements a value-based equality comparison that is similar to Mathematica's SameQ. |
| Inequality Operator | Implements a value-based inequality comparison. |
| Explicit Expr to Double Conversion | Converts the Expr to a double value. This is the same operation as calling the AsDouble method. |
| Explicit Expr to Int64 Conversion | Converts the Expr to a long integer value. This is the same operation as calling the AsInt64 method. |
| Explicit Expr to String Conversion | Converts the Expr to a string representation. This is the same operation as calling the ToString method. |
Public Instance Constructors
|
Expr
|
Overloaded. Creates a new Expr object. |
Public Instance Properties
 Args | Gets an array of Exprs representing the arguments of this Expr. |
| Dimensions | Gets an array of integers representing the dimensions of this Expr. Works like the Mathematica function Dimensions. |
| Head | Gets the Expr representing the head of this Expr. Works like the Mathematica function Head. |
| Item | Gets a part based on its position index. This is the indexer for the class. |
| Length | Gets the length of this Expr. Works like Mathematica's Length function. |
Public Instance Methods
| AsArray | Converts the Expr to an array of the requested type and depth. |
| AsDouble | Gives the double value for Exprs that can be represented as doubles. |
| AsInt64 | Gives the Int64 value for Exprs that can be represented as integers. |
| AtomQ | Tells whether the Expr represents a Mathematica atom. Works like the Mathematica function AtomQ. |
| ComplexQ | Tells whether the Expr represents a Mathematica Complex number. |
| Delete | Returns a new Expr that has the same head but the nth element deleted (counted from the end if n is negative). Works like the Mathematica function Delete. |
| Dispose | Frees resources that the Expr uses internally. |
| Equals | Implements a value-based equality comparison that is similar to Mathematica's SameQ. |
| GetHashCode | |
| GetObjectData | Populates the SerializationInfo object with the Expr's internal state information. |
| GetType (inherited from Object) | |
| Insert | Returns a new Expr that has the same head but with e inserted into position n (counted from the end if n is negative). Works like the Mathematica function Insert. |
| IntegerQ | Tells whether the Expr represents a Mathematica integer. Works like the Mathematica function IntegerQ. |
| ListQ | Tells whether the Expr represents a Mathematica list (that is, it has head List). Works like the Mathematica function ListQ. |
| MatrixQ | Overloaded. Tells whether the Expr represents a Mathematica matrix (that is, it has head List, every element has head List, and no deeper parts are themselves lists). Works like the Mathematica function MatrixQ. |
| NumberQ | Tells whether the Expr represents a Mathematica number (real, integer, rational, or complex). Works like the Mathematica function NumberQ. |
| Part | Overloaded. Gives the Expr representing the specified part of this Expr. Works like the Mathematica function Part. |
| Put | Not intended for general use. |
| RationalQ | Tells whether the Expr represents a Mathematica Rational number. |
| RealQ | Tells whether the Expr represents a Mathematica Real number. |
| StringQ | Tells whether the Expr represents a Mathematica string. Works like the Mathematica function StringQ. |
| SymbolQ | Tells whether the Expr represents a Mathematica symbol. |
| Take | Returns a new Expr that has the same head but only the first n elements of this Expr (or last n elements if n is negative). Works like the Mathematica function Take. |
| ToString | Returns a representation of the Expr as a Mathematica InputForm string. |
| TrueQ | Tells whether the Expr represents the Mathematica symbol True. Works like the Mathematica function TrueQ. |
| VectorQ | Overloaded. Tells whether the Expr represents a Mathematica vector (that is, it has head List, and no parts are themselves lists). Works like the Mathematica function VectorQ. |
