+# Flee (Supports Net6.0, Net5.0, Netstandard2.1, Netstandard2.0)
+ Fast Lightweight Expression Evaluator.
+ Convert this project vb.net to c#.
+  
+ ## Project Description
+Flee is an expression parser and evaluator for the .NET framework. It allows you to compute the value of string expressions such as sqrt(a^2 + b^2) at runtime. It uses a custom compiler, strongly-typed expression language, and lightweight codegen to compile expressions directly to IL. This means that expression evaluation is extremely fast and efficient.
+
+## Features
+* Fast and efficient expression evaluation
+* Small, lightweight library
+* Compiles expressions to IL using a custom compiler, lightweight codegen, and the DynamicMethod class
+* Expressions (and the IL generated for them) are garbage-collected when no longer used
+* Does not create any dynamic assemblies that stay in memory
+* Backed by a comprehensive suite of unit tests
+* Culture-sensitive decimal point
+* Fine-grained control of what types an expression can use
+* Supports all arithmetic operations including the power (^) operator
+* Supports string, char, boolean, and floating-point literals
+* Supports 32/64 bit, signed/unsigned, and hex integer literals
+* Features a true conditional operator
+* Supports short-circuited logical operations
+* Supports arithmetic, comparison, implicit, and explicit overloaded operators
+* Variables of any type can be dynamically defined and used in expressions
+* CalculationEngine: Reference other expressions in an expression and recalculate in natural order
+* Expressions can index arrays and collections, access fields and properties, and call functions on various types
+* Generated IL can be saved to an assembly and viewed with a disassembler
