如何在ASP.NET中更改日期格式？

TextBox1

TextBox2

Button1

TextBox1

var parsedDateTime = DateTime.ParseExact(
    textBox1.Text, \"dd/MM/yyyy\", CultureInfo.InvariantCulture);

TextBox

var textBox2.Text = parsedDateTime.ToString(\"yyyy/MM/dd\");

dd/MM/yyyy

d/M/yyyy

var textBox1 = new TextBox { Text = \"2/3/2004\" };
var parsedDateTime = DateTime.ParseExact(textBox1.Text, \"d/M/yyyy\", CultureInfo.InvariantCulture);

var textBox2 = new TextBox();
textBox2.Text = parsedDateTime.ToString(\"yyyy/MM/dd\");
