You have wanted create dynamic button and give dynamic button name and event like button text, click event e.t.c...

where have you wanted to make dynamic button. I think you will generate dynamic button in side the loop. I side the loop you will create a button object like...

In The web form example............
create a panel to add dynamic button in the ".aspx" page

Code of snippet of code ..

for (int i = 0; i < 10; i++)
{
Button newLabelSection = new Button();
// bug fix 0000013
newLabelSection.Text = i.ToString();
newLabelSection.ID ="btn"+i;
newLabelSection.Height = 40;
newLabelSection.Width = 50;
newLabelSection.Click += new System.EventHandler(this.sectionListItem_Click);
Panel1.Controls.Add(newLabelSection);

}

protected void sectionListItem_Click(object sender,EventArgs e)
{
var text = ((Button)sender).Text;
}

Another example of winform ......

for (int i = 0; i < 10; i++)
{
Button newLabelSection = new Button();
newLabelSection.Text = i.Tostring();
newLabelSection.Size = new System.Drawing.Size(40, 50);
newLabelSection.Location = new System.Drawing.Point(sectionListPanel.Width, 0);
newLabelSection.Margin = new System.Windows.Forms.Padding(3);
newLabelSection.UseVisualStyleBackColor = true;
newLabelSection.Tag = i;
newLabelSection.Click += new System.EventHandler(this.sectionListItem_Click);
sectionListPanel.Controls.Add(newLabelSection);
}

protected void sectionListItem_Click(object sender,EventArgs e)
{
var text = ((Button)sender).Text;
}

I think this is use full for you.
If agree, kindly accept the answer.

Try with below code:
//Counter for Dynamic Buttons.
int DynamicButtonCount = 1;

// This event generates Dynamic Buttons.
private void btnGenerate_Click(object sender, EventArgs e)
{
   string name = "Button" + DynamicButtonCount;
   Button btnDynamicButton = new Button();
   btnDynamicButton.Name = name;
   btnDynamicButton.Text = name;
   btnDynamicButton.Size = new System.Drawing.Size(200, 30);
   btnDynamicButton.Location = new System.Drawing.Point(40, DynamicButtonCount * 40);
   btnDynamicButton.Click += new EventHandler(this.btnDynamic_Click);
   Controls.Add(btnDynamicButton);
   DynamicButtonCount++;
}

// This event is triggered when a Dynamic Button is clicked.
protected void btnDynamic_Click(object sender, EventArgs e)
{
   Button dynamicButton = (sender as Button);
   MessageBox.Show("You clicked: " + dynamicButton.Name);
}
