c# - 连接到 SQL Server 时出现 "Illegal characters in path"错误

Question

我正在尝试连接到数据库，但出现以下错误:

Illegal characters in path.

这是我的代码:

private void button1_Click(object sender, EventArgs e)
{
    SqlConnection Con = new SqlConnection("Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\targil3.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True");
    SqlDataAdapter adapt = new SqlDataAdapter();
    adapt.InsertCommand = new SqlCommand(" INSERT INTO tblEmployee VALUES (@employeeNumber, @employeePrivateName, @employeeFamilyName ,@city, @street, @houseNo, @phoneNumber, @birthDate, @startWorkingDate)", Con);
    adapt.InsertCommand.Parameters.Add("@employeeNumber", SqlDbType.Char).Value = textBox1.Text;
    adapt.InsertCommand.Parameters.Add("@employeePrivateName", SqlDbType.VarChar).Value = textBox2.Text;
    adapt.InsertCommand.Parameters.Add("@employeeFamilyName", SqlDbType.VarChar).Value = textBox3.Text;
    adapt.InsertCommand.Parameters.Add("@city", SqlDbType.VarChar).Value = textBox4.Text;
    adapt.InsertCommand.Parameters.Add("@street", SqlDbType.VarChar).Value = textBox5.Text;
    adapt.InsertCommand.Parameters.Add("@houseNo", SqlDbType.Int).Value = textBox6.Text;
    adapt.InsertCommand.Parameters.Add("@phoneNumber", SqlDbType.Char).Value = textBox7.Text;
    adapt.InsertCommand.Parameters.Add("@birthDate", SqlDbType.DateTime).Value = Convert.ToDateTime(textBox8.Text);
    adapt.InsertCommand.Parameters.Add("@startWorkingDate", SqlDbType.DateTime).Value = Convert.ToDateTime(textBox8.Text);


    Con.Open();
    adapt.InsertCommand.ExecuteNonQuery();
    Con.Close();
}

如何连接到数据库以便将数据插入其中？

Answer 1

你需要转义 \targil3.mdf

例如，使用\\ 或在字符串赋值前放置一个@。

SqlConnection Con = new SqlConnection(@"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\targil3.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True");
