Methods

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Declaration
public void Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Declaration
protected virtual void Dispose(bool disposing)
Parameters
System.Boolean disposing

Parse(String)

Converts the string representation of an expression to its System.Linq.Expressions.LambdaExpression equivalent.

Declaration
public LambdaExpression Parse(string expression)
Parameters
System.String expression

The string expression to be parsed.
Returns
System.Linq.Expressions.LambdaExpression

Exceptions
ExpressionParserException

ExpressionParserException.

ParseAsync(String)

Run a parse operation and returns the resulting lambda expression.

Declaration
public Task<LambdaExpression> ParseAsync(string expression)
Parameters
System.String expression

The string expression to be parsed.
Returns
System.Threading.Tasks.Task<System.Linq.Expressions.LambdaExpression>

Exceptions
ExpressionParserException

ExpressionParserException.

ParseAsync(String, CancellationToken)

Run a parse operation and returns the resulting lambda expression.

Declaration
public Task<LambdaExpression> ParseAsync(string expression, CancellationToken cancellationToken)
Parameters
System.String expression

The string expression to be parsed.
System.Threading.CancellationToken cancellationToken

The cancellation token that will be assigned to the new task.
Returns
System.Threading.Tasks.Task<System.Linq.Expressions.LambdaExpression>

Exceptions
ExpressionParserException

ExpressionParserException.

TryParse(String, out LambdaExpression)

Converts the string representation of an expression to its System.Linq.Expressions.LambdaExpression equivalent. A return value indicates whether the conversion succeeded or failed.

Declaration
public bool TryParse(string expression, out LambdaExpression lambda)
Parameters
System.String expression

A string containing an expression to convert.
System.Linq.Expressions.LambdaExpression lambda

When this method returns, contains the System.Linq.Expressions.LambdaExpression equivalent of the s parameter, if the conversion succeeded, or null if the conversion failed. The conversion fails when the supplied expression contains invalid operators or operands;any value originally supplied in result will be overwritten.
Returns
System.Boolean

true if expression was converted successfully; otherwise, false.
