Condition:

IF A > B THEN

PRINT B

ELSE

PRINT A

This condition is written as a string in coloumn of the table in SQL.

I want to fetch this condition from the table and convert this condition to the C# Code as

If(A > B )

{

print B...........

}

else

{

print A...........

}

Where A and B are the Dynamic values passed in the C#.

For this purpose the expression evaluator can be used.
This article may be helpful to you

math / function / boolean /string expression evaluator[^]

From the following paragraph of the above article

"Thus, I've developed a set of simple classes called ExpressionEval and FunctionEval. These evaluators handle numeric, string, boolean, and datetime datatypes, and they support all the unary and binary operators available in C#. They also support functions (through the utilization of FunctionEval class) and have the ability to add custom functions by attaching an event handler that fires when a function name is not found."

it can be seen that strings can be handled.
