No.

DllImport is for unmnaged code.

for managed code you should:
- add a reference to your project
- want a "using" statetement
- use the managed classes as if they are inside your EXE

Just like any EXE locates functions in some DLL: searching the exported symbols table by name (there is a scheme using "ordinal numbers" too, AFAIK CLR doesn't use that).

The DllImport directive specifies the DLL name, the Windows system environment variable "PATH" tells which folders to search, the optional "EntryPoint" parameter inside DllImport allows you to rename the function.

Hi,

you need some variables when reading from the console. Here is a way to get a number (note the use of PRE tags for readability):

Console.WriteLine("please enter number:");
string s=Console.ReadLine();
int number;
bool OK=int.TryParse(s, out number);
if (OK) {
    Console.WriteLine("You entered the number "+number);
} else {
    Console.WriteLine("Unacceptable input: "+s);
}

Hi,

what brackets? do you mean the parentheses?

did you put your code inside a method, the method inside a class, the class inside a namespace?

if there is an error message, give it as is.
if it specifies a line number, check that line.
work on the first error message first.
and teach your IDE to always show line numbers, see #102 here[^]

Dear Luc Pattyn,

I have fixed this problem, the problem was that one of the settings for c# was changed. I dont know how that happened. I just reset all the settings to default and that worked.

Thank you very much for helping,
Aman

What you can do is:
- add "(SOLVED)" to the subject line of the original post
- click "good answer" on the reply that did it for you (that removes it from the "unanswered questions" list)

hello everyone out there!
I have one problem and I hope someone can help me. There is one project what I am working on and is mostly data scraping and saving data in xml document. I have an option to create lists and then add data to the lists. For example, the user can create list for restaurants, and I am creating xml document just with one xml element: <restaurants>.
Then once I have all the data scraped I want to add xml nodes with the data what I have to the existing document. I am trying something like this:

string path = Properties.Settings.Default.XMLFolder + list + ".xml";
            XmlTextReader rdr = new XmlTextReader(path);
            XmlDocument doc = new XmlDocument();
            doc.Load(rdr);
 XmlNode nodeBusiness = doc.CreateNode(XmlNodeType.Element, "Business", string.Empty);
            nodeBusiness.Attributes.Append(attribute);
            docData.AppendChild(nodeBusiness);

I am getting an error at the last step: "This document already has a 'DocumentElement' node."

Can someone help me to solve this issue, thanks in advance. Laziale
