Method	Description
AddDebugInfo ( Expression expression, SymbolDocumentInfo document, SourceLocation start, SourceLocation end ) : Expression
AddDebugInfo ( Expression expression, SymbolDocumentInfo document, int startLine, int startColumn, int endLine, int endColumn ) : Expression
Box ( Expression expression ) : Expression	Returns an expression that boxes a given value. Uses boxed objects cache for Int32 and Boolean types.
Coalesce ( Expression left, Expression right, ParameterExpression &temp ) : Expression	Null coalescing expression {result} ::= ((tmp = {_left}) == null) ? {right} : tmp '??' operator in C#.
Coalesce ( LambdaBuilder builder, Expression left, Expression right ) : Expression
CoalesceFalse ( Expression left, Expression right, MethodInfo isTrue, ParameterExpression &temp ) : Expression	False coalescing expression. {result} ::= IsTrue(tmp = {left}) ? tmp : {right} Generalized OR semantics.
CoalesceFalse ( LambdaBuilder builder, Expression left, Expression right, MethodInfo isTrue ) : Expression	False coalescing expression. {result} ::= IsTrue(tmp = {left}) ? tmp : {right} Generalized OR semantics.
CoalesceTrue ( Expression left, Expression right, MethodInfo isTrue, ParameterExpression &temp ) : Expression	True coalescing expression. {result} ::= IsTrue(tmp = {left}) ? {right} : tmp Generalized AND semantics.
CoalesceTrue ( LambdaBuilder builder, Expression left, Expression right, MethodInfo isTrue ) : Expression	True coalescing expression. {result} ::= IsTrue(tmp = {left}) ? {right} : tmp Generalized AND semantics.
ComplexCallHelper ( MethodInfo method ) : Expression	The complex call helper to create the AST method call node. Will add conversions (Expression.Convert()), deals with default parameter values and params arrays.
Convert ( Expression expression, Type type ) : Expression
DebugMarker ( string marker ) : Expression
FinallyFlowControl ( Expression body ) : Expression
GetLValueAccess ( this type ) : ExpressionAccess	Determines if the left child of the given expression is read or written to or both.
If ( IfStatementTest tests, Expression @else ) : Expression
If ( ) : IfStatementBuilder
If ( Expression test ) : IfStatementBuilder
If ( Expression test, Expression body ) : IfStatementBuilder
IfThen ( Expression test ) : Expression
IfThen ( Expression test, Expression body ) : Expression
IfThenElse ( Expression test, Expression body, Expression @else ) : Expression
Infinite ( Expression body ) : LoopExpression
Infinite ( Expression body, LabelTarget @break, LabelTarget @continue ) : LoopExpression
IsAssignment ( this type ) : bool	Determines whether specified expression type represents an assignment. Note that some other nodes can also assign to variables, members or array items: MemberInit, NewArrayInit, Call with ref params, New with ref params, Dynamic with ref params.
IsLValue ( this type ) : bool
IsReadWriteAssignment ( this type ) : bool
IsWriteOnlyAssignment ( this type ) : bool
Loop ( Expression test, Expression increment, Expression body, Expression @else ) : LoopExpression
Loop ( Expression test, Expression increment, Expression body, Expression @else, LabelTarget @break, LabelTarget @continue ) : LoopExpression
NewArrayHelper ( Type type, IEnumerable initializers ) : NewArrayExpression
SimpleCallHelper ( Expression instance, MethodInfo method ) : MethodCallExpression	The helper to create the AST method call node. Will add conversions (Utils.Convert) to parameters and instance if necessary.
SimpleCallHelper ( MethodInfo method ) : MethodCallExpression	The helper to create the AST method call node. Will add conversions (Utils.Convert) to parameters and instance if necessary.
Try ( ) : TryStatementBuilder
Try ( Expression body ) : TryStatementBuilder
Try ( Expression expr0, Expression expr1 ) : TryStatementBuilder
Try ( Expression expr0, Expression expr1, Expression expr2 ) : TryStatementBuilder
Try ( Expression expr0, Expression expr1, Expression expr2, Expression expr3 ) : TryStatementBuilder
Unless ( Expression test, Expression body ) : Expression
Update ( this expression, Expression left, Expression right ) : BinaryExpression
Void ( Expression expression ) : Expression	Converts an expression to a void type.
While ( Expression test, Expression body, Expression @else ) : LoopExpression
While ( Expression test, Expression body, Expression @else, LabelTarget @break, LabelTarget @continue ) : LoopExpression
