Title
Body
I have two expression trees defined like this: private Expression<Func<TEntity, TPropertyResult>> PropertyAccessor { get; set; } and private Expression<Func<TPropertyResult, bool>> TestExpression { get; set; } I need to create a new expression tree that will result in the equivalent of: var expression = p => this.TestExpression(this.PropertyAccessor(p)); When using Expression.Invoke(this.TestExpression, this.PropertyAccessor) , I get the following error {"Expression of type 'System.Func`2[MyEntity,System.String]' cannot be used for parameter of type 'System.String'"} TPropertyResult is a string during my test. I tried using Expression.Call or Expression.Invoke . No luck. What should I use?
