参数化查询需要参数'@units'，这是未提供的

Question

我遇到了这个例外：

  

System.Data.SqlClient.SqlException：'参数化查询'（@ Date datetime，@ Type nvarchar（11），@ Registration nvarchar（6），@ De'需要参数'@SyntDate'，这是未提供的。“

我的插入代码是：

private void simpleButton1_Click(object sender, EventArgs e)
{
    if (baglanti.State == ConnectionState.Closed)
    {
        baglanti.Open();

        SqlCommand cmd = new SqlCommand(@"INSERT INTO LogBook
