推荐答案

DateTime dt = DateTime.Now;

// Change "5" to the day you are interested in
if (dt.Day == 5)
{
    // enable button
}
else
{
    // disable button
}

写入页面加载事件

Write in the page load event

protected void Page_Load(object sender, EventArgs e)
        {
            int dayToEnable = 10; // 10th of every month
            btnID.Enabled = false;
            if (DateTime.Today.Day == dayToEnable)
                btnID.Enabled = true;
        }
