Cannot take the address of, get the size of, or declare a pointer to a managed type ('type name')
this error stops compiling if i have one or more System.String in my structs
is there any other way to store strings?i have tried things like this:
private long _B_ID;
private开发者_如何学Go byte[] _C_Name;
private byte[] _C_Address;
private byte[] _C_Telephone;
but it is not seeming to work.
You can only get the address of a struct if it is blittable, i.e. it doesn't contain references.
See Blittable and Non-Blittable Types(MSDN)
You can not declare a Pointer to Non-fixed types even if you use "unsafe". To remove this error, You HAVE to specify size of the arrays along with keyword fixed.
For Example, _C_Name contains 25 bytes. So declare it as:
private fixed byte _C_Name[25];
Strings are Fixed typed so you was not getting error when you declare them as String. Hope it works for you!
Regards!
Try the MarshalAs
attribute:
struct Foo
{
[MarshalAs(UnmanagedType.LPStr]
string s;
}
