QUESTION
I'm trying to insert a list of file names into a simple Sql Server table.
I'm trying to leverage SqlBulkCopy and @markgravell's FastMember library, as suggested by other SO answers.
...ANSWER
Answered 2017-Mar-03 at 03:31I have never used this Library before however reviewing the GitHub source code it it requires a property to query from the source. Now on a string there isn't a property value
really all you have to use is the Length
property. Using Length
. Now this may be an issue with the FastMember library, where it creates a CallSite
accessor function to capture the Property from the target object.
Now I have had a play and cannot get access to any property that will work. At first glance their is a Chars
property being returned in the TypeAccessor
results but this does not appear to work.
My suggestion is not really an answer to the question but a way to make it work. If you created a type that had a Property of the string then you could effectively get around this.
QUESTION
I have the following method which sets the value for the given PropertyInfo
on the given TInstance
. This is to avoid the inefficiency of reflection.

Answered 2017-Jan-10 at 17:33As noted in the comments, you really shouldn't create mutable structs. However, to answer the question, structs are value types and therefore a copy of your struct is passed to the Action
and therefore the original person value is not changed.
You need a way to pass the struct
by reference. However, expressions do not support creating "methods" that take parameters by reference.
What you can do is use the DynamicMethod
class to do something like this:
