Stored procedure error with ADO.NET - stored-procedures

Question

I have a situation here. My stored procedure works exactly fine the way I want in SQL Server.
However, I'm unable to implement the same in ADO.NET.
Here is my stored procedure:
Create Procedure bridge_Type(
#EmpID INT,
#Name varchar(50),
#Mob2 numeric(10,0),
#Email varchar(50),
#Type varchar(50)
)
AS
DECLARE #TYPEID int
Set NOCOUNT OFF
BEGIN TRANSACTION
INSERT INTO dbo.EmpType VALUES (#Type)
SET #TYPEID = SCOPE_IDENTITY()
IF ##ERROR <> 0
BEGIN
ROLLBACK
RETURN
END
Insert into dbo.Emp VALUES (#EmpID, #Name, #Mob2, #Email, #TYPEID)
IF ##ERROR <> 0
BEGIN
ROLLBACK
RETURN
END
COMMIT
Here is my ADO.NET connections for simple registration process.
public void InsertInfo()
{
String empdb = #"Data Source=USER-PC\SQLEXPRESS;Initial Catalog=EmployeeDB;Integrated Security=True";
SqlConnection conn = new SqlConnection(empdb);
SqlCommand cmd = new SqlCommand("bridge_Type", conn);
cmd.CommandType = CommandType.StoredProcedure;
try
{
conn.Open();
/*cmd.Parameters.Add(new SqlParameter("#EmpID", TextBox1.Text));
cmd.Parameters.Add(new SqlParameter("#Name", TextBox2.Text));
cmd.Parameters.Add(new SqlParameter("#Mob2", TextBox3.Text));
cmd.Parameters.Add(new SqlParameter("#Email", TextBox4.Text));
cmd.Parameters.Add(new SqlParameter("#Emptype", dropdown1.SelectedValue));
cmd.Parameters.Add(new SqlParameter("#Emptype", SqlDbType.VarChar, 50));
cmd.Parameters("#Emptype").Value = dropdown1.SelectedValue; */
cmd.Parameters.Add(new SqlParameter("#EmpID", SqlDbType.Int));
cmd.Parameters["#EmpID"].Value = Convert.ToInt32(TextBox1.Text);
cmd.Parameters.Add(new SqlParameter("#Name", SqlDbType.VarChar, 50));
cmd.Parameters["#Name"].Value = TextBox2.Text;
cmd.Parameters.Add(new SqlParameter("#Mob2", SqlDbType.Int));
cmd.Parameters["#Mob2"].Value = TextBox3.Text;
cmd.Parameters.Add(new SqlParameter("#Email", SqlDbType.VarChar, 50));
cmd.Parameters["#Email"].Value = TextBox4.Text;
cmd.Parameters.Add(new SqlParameter("#Emptype", SqlDbType.VarChar, 50));
cmd.Parameters["#Emptype"].Value = dropdown1.SelectedValue;
cmd.ExecuteNonQuery();
}
catch (System.Data.SqlClient.SqlException ex)
{
string msg = "Insert Error:";
msg += ex.Message;
throw new Exception(msg);
}
finally
{
if (conn != null)
{
conn.Close();
}
}
}
protected void Button1_Click(object sender, EventArgs e)
{
InsertInfo();
}

It looks like you missed a conversion to an int in your #Mob2 parameter:
cmd.Parameters.Add(new SqlParameter("#Mob2", SqlDbType.Int));
cmd.Parameters["#Mob2"].Value = Convert.ToInt32(TextBox3.Text);
EDIT:
Thanks to David for seeing this. The last parameter you are adding is called #Emptype, but the stored proc is expecting it to be named #Type.
