【问题描述】：
我用 sql db 在 c# 中创建了一个应用程序，当我在应用程序中保存数据时，在“system.argumentException”中显示错误“初始化字符串的格式不符合从索引 73 开始的规范”
我使用 windows autentication 和此代码进行连接：
public static SqlConnection ObtenerConexion()
{
SqlConnection Conn = new SqlConnection("Data source=VICTOR-PC; Initial Catalog=KAZIIM; Integrated Security=True;");
Conn.Open();
return Conn;
}
}
保存数据按钮的代码是：
private void btnGuardar_Click(object sender, EventArgs e)
{
Cliente Cliente = new Cliente();
Cliente.ID_C = int.Parse(txtID.Text);
Cliente.NOMBRES = txtNombres.Text;
Cliente.CONTACTO = txtCorreo.Text;
Cliente.CALLE = txtCalle.Text;
Cliente.NUMERO = int.Parse(txtNumero.Text);
Cliente.COLONIA = txtColonia.Text;
Cliente.FECHA_ALTA = txtFecha.Text;
int resultado = ClienteDAL.Agregar(Cliente);
if (resultado > 0)
{
MessageBox.Show("Datos guardados con exito", "Datos Guardado", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
else
{
MessageBox.Show("No se grabaron los datos", "Error al guardar", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
异常详情是：

【问题讨论】：
-
这个异常到底在哪一行？
-
嗨！在这个：SqlConnection Conn = new SqlConnection("Data source=VICTOR-PC; Initial Catalog=KAZIIM; Integrated Security=True;");
-
尝试删除多余的空格和最后一个“;”。该错误表示第 73 个字母有一些错误。会不会有一些字母显示不正确？将您的代码行粘贴到记事本中，然后返回到您的代码中以消除“隐藏”字母。甚至更好。再次写入该行，无需任何复制/粘贴。
