我无法在使用linkbutton的ASP中使用sweetalert进行确认

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/sweetalert2@11.1.4/dist/sweetalert2.min.css">
<script src="https://cdn.jsdelivr.net/npm/sweetalert2@11.1.4/dist/sweetalert2.all.min.js"></script>

protected void LinkButton_Click(object sender, EventArgs e)
{
    string script = @"<script>
                        Swal.fire({
                            title: '确认',
                            text: '你确定要执行此操作吗？',
                            icon: 'warning',
                            showCancelButton: true,
                            confirmButtonText: '确定',
                            cancelButtonText: '取消'
                        }).then((result) => {
                            if (result.isConfirmed) {
                                // 确认操作的逻辑代码
                            }
                        });
                    </script>";
    ClientScript.RegisterStartupScript(this.GetType(), "confirm", script);
}
