Display List in windows forms application

Farhan Shariff

I want to Display results of the list .
Is it possible to display the list in console (program is windows form)as list excludedNames has many values. Which is the best way to display the result.?.

Collapse | Copy Code
private void bt_compare_Click(object sender, EventArgs e)
{
table1 = GetDataTabletFromCSVFile(tbCSVPath.Text);
table2 = GetDataTabletFromCSVFile1(tbCSVPath1.Text);
List<string> excludedNames = new List<string>();

for (int i = 0; i < table1.Rows.Count; i++)
{
string col = table1.Rows[i]["Par Name"].ToString();

if (!table2.Columns.Contains(col))
{
excludedNames.Add(col);
}
}
}

You could use a ListBox:

listBox1.DataSource = excludedNames;

or a multi-line TextBox:

textBox1.Lines = excludedNames.ToArray();

or a MessageBox:

string message = String.Join("\r\n", excludedNames.ToArray());
MessageBox.Show(message);

Sure, try this:

var query = excludedNames.Select((s,i) => String.Format("{0, -2} {1}", i + 1, s));
richTextBox1.Lines = query.ToArray();

If there are likely to be more than 99 elements in the list then replace -2 with -3.

textbox works perfectly, I am using richTextbox1. I want to add line number to the richTextBox1. like line numbering the richTextBox1 for each entry.so that I know how many entries are there.

I want to display those columns which are missing. What are the other better options which are available.

If you're just wanting to do this for debugging purposes, then you can attach a console to a windows forms application by right clicking your project in Solution Explorer, selecting Properties from the drop down list and then (under the Application tab) setting the Output type to Console application.

This will enable you to use Console.WriteLine to display the elements of the list.
