I'm getting this error while inserting data from my form to database using LinQ

When I enter the object of the class(e.g: Employee empObj = new Employee()) It shows the error.

using (DataClass1DataContext DcContext = new DataClass1DataContext())
                {
                    ArticleMdl articleObj = new ArticleMdl();
                    articleObj.Title = TextBox1.Text;
                    articleObj.Summary = TextBox2.Text;
                    articleObj.Tags = TextBox3.Text;
                    articleObj.Image = TextBox4.Text;
                    articleObj.Category = Convert.ToInt32(RadioButtonList1.SelectedValue);
                    articleObj.Subcategory = Convert.ToInt32(RadioButtonList2.SelectedValue);
                    
                    DcContext.tblArticles.InsertOnSubmit(articleObj);
                    DcContext.SubmitChanges();
                    Label1.Text = "Your article is saved.";
                }

Error 1 The best overloaded method match for 'System.Data.Linq.Table.InsertOnSubmit(Linqtosql1.tblArticle)' has some invalid arguments

Please do reply how to recover it.

What I have tried:

Tried to insert on putting of direct values to the properties. The same error arose.

From the error it looks like you are passing the wrong object for insert.

Use valid arguments for method calls and your problem will be solved.

using (DataClass1DataContext DcContext = new DataClass1DataContext())
{
ArticleMdl articleObj = new ArticleMdl();
articleObj.Title = TextBox1.Text;
articleObj.Summary = TextBox2.Text;
articleObj.Tags = TextBox3.Text;
articleObj.Image = TextBox4.Text;
articleObj.Category = Convert.ToInt32(RadioButtonList1.SelectedValue);

Solution 1

The object you're passing to the method is not of or derived from type TEntity.
