Dear reader,

In my code I get the following error:

AddComment.cs(32): The best overloaded method match for
'WebLogger.Message.SelectMessage(string, out string, out string)' has some
invalid arguments

This is the code:


class Message
{
...
public int SelectMessage(string pID, out string pTitle, out string
pAddedDate)
{
...
}
}

class AddComment
{
...
public void InsertComment(int pMessageID, string pAuthor, string pEmail,
string pComment)
{
string msgTitle, msgAddedDate;
Message msg = new Message();
msg.SelectMessage(pMessageID, out msgTitle, out msgAddedDate);
}
}

Does anybody have an idea?
I'm quite new to C#, so this could easily be something stupid.

Thanks in advance,

Eddy de Boer

SelectMessage requires a string as the first parameter, you are trying to
pass in int (pMessageID). You need to convert that int to a string first,
easily done by using pMessageID.ToString().
 
Hi,

InsertComment uses

int pMessageID

but SelectMessage uses

string pID

Either change SelectMessage to use int pID, or use pMessage.ToString() when calling SelectMessage

Well, pMessageID is an int, and you're trying to pass it in as a
string. What do you want to do with it? You could call ToString() on
pMessageID if you want:

msg.SelectMessage(pMessageID.ToString(),
out msgTitle,
out msgAddedDate);
