Syntax

public sealed class ExpressionDescription : IEquatable<ExpressionDescription>

Constructors

ExpressionDescription(String, IEnumerable<AssemblyReference>, IEnumerable<UsingNamespace>, IEnumerable<String>, IEnumerable<VariableType>)

Initializes a new instance of ExpressionDescription.

Declaration

public ExpressionDescription(string expression, IEnumerable<AssemblyReference> assemblyReferences, IEnumerable<UsingNamespace> usingNamespaces, IEnumerable<string> inScopeVariableNames, IEnumerable<VariableType> typeDesignations)

Parameters

Type	Name	Description
System.String	expression	The expression body.
System.Collections.Generic.IEnumerable<AssemblyReference>	assemblyReferences	The assembly references.
System.Collections.Generic.IEnumerable<UsingNamespace>	usingNamespaces	The using namespaces.
System.Collections.Generic.IEnumerable<System.String>	inScopeVariableNames	A collection of the names of variables which are in-scope for this expression.
System.Collections.Generic.IEnumerable<VariableType>	typeDesignations	A collection of variable-type-designations.

Properties

AssemblyReferences

Gets a collection of the assembly references which should be available when the expression is evaluated.

Declaration

public IReadOnlyCollection<AssemblyReference> AssemblyReferences { get; }

Property Value

Type	Description
System.Collections.Generic.IReadOnlyCollection<AssemblyReference>

Expression

Gets the body of the expression itself. This is an executable C# script.

Declaration

public string Expression { get; }

Property Value

Type	Description
System.String	The expression body.

InScopeVariableNames

Gets a collection of the names of variables which are in-scope for this expression.

Declaration

public IReadOnlyCollection<string> InScopeVariableNames { get; }

Property Value

Type	Description
System.Collections.Generic.IReadOnlyCollection<System.String>

TypeDesignations

Gets a collection of variable-type-designations. These indicate any variables which should be treated as strongly-typed instances and not as dynamic objects.

Declaration

public IReadOnlyCollection<VariableType> TypeDesignations { get; }

Property Value

Type	Description
System.Collections.Generic.IReadOnlyCollection<VariableType>

UsingNamespaces

Gets a collection of the using namespaces which should be 'in scope' when the expression is evaluated.

Declaration

public IReadOnlyCollection<UsingNamespace> UsingNamespaces { get; }

Property Value

Type	Description
System.Collections.Generic.IReadOnlyCollection<UsingNamespace>

Methods

Equals(Object)

Gets a value which indicates if the current instance is equal to the specified System.Object.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
System.Object	obj	An object.

Returns

Type	Description
System.Boolean	true if the instances are equal; false otherwise.

Overrides

System.Object.Equals(System.Object)

Equals(ExpressionDescription)

Gets a value which indicates if the current instance is equal to the specified ExpressionDescription.

Declaration

public bool Equals(ExpressionDescription other)

Parameters

Type	Name	Description
ExpressionDescription	other	An expression specification.

Returns

Type	Description
System.Boolean	true if the instances are equal; false otherwise.

GetHashCode()

Gets a hash code for the current instance.

Declaration

public override int GetHashCode()

Returns

Type	Description
System.Int32	The hash code.

Overrides

System.Object.GetHashCode()

ToString()

Gets a string which represents the current instance.

Declaration

public override string ToString()

Returns

Type	Description
System.String	The string representation.

Overrides

System.Object.ToString()
