        this.label5.Name = "label5";
        this.label5.Size = new System.Drawing.Size(28, 13);
        this.label5.TabIndex = 5;

        this.textBox3.Size = new System.Drawing.Size(44, 20);
        this.textBox3.TabIndex = 7;
        // 
        // Form2
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(751, 428);
        this.Controls.Add(this.textBox3);
        this.Controls.Add(this.textBox2);
        this.Controls.Add(this.label5);
        this.Controls.Add(this.label4);
        this.Controls.Add(this.label3);
        this.Controls.Add(this.label2);
        this.Controls.Add(this.textBox1);
        this.Controls.Add(this.label1);

Sorry if that’s too long, how can i do it?

Answer 1

You can add many controls without specifying the name. for instance:

private void DynamicAddTextBoxes(Point startLocation, count)
{
    Point location = startLocation;
    for (int textBoxIndex = 0; textBoxIndex < count; textBoxIndex++)
    {
        TextBox textBox = new TextBox();
        textBox.Text = textBoxIndex.ToString();
        textBox.Location = new Point(location.X, location.Y + 50);
        this.Controls.Add(textBox );
    }
}

This code will add sequence of TextBoxes to the form.
