I am working with system.linq.dynamic.core and nhibernate linq. Now I want to pass two dynamic linq expression to a method. One for the parent table and one for a joined child list. The input parameter for both expressions are random, so an expression could be
"x => x.Name == \"Wick\" "
" k => k.FirstName = \"John\" "
Now I know that with dynamic linq you could parse the string expressions to a LambdaExpression.
If I want to create a join there has to be an alias for the joined table. So from the expression I would like to extract the 'x' or the 'k'. Is this possible?
LambdaExpression has a
Parameters property, which you can use to access information about lambda's parameters. In your case, that could be something like:
string GetParameterName(LambdaExpression expression) => expression.Parameters.Single().Name;
