Incorrect SQL syntax error ADO.NET - sql-server

Question

When I try to run this i get an SqlException with the message "Incorrect syntax near the keyword 'PROCEDURE'."
120: cmd.CommandText = #"CREATE PROCEDURE FindState #Name nvarchar(50)
AS SELECT IDState FROM State WHERE Name=#Name";
121: cmd.ExecuteNonQuery();
Stack trace:

However I tried copying the SQL command directly in a SQL query and executing it and it worked. (it created the procedure)
To give you some context here is a little bigger section of the code
SqlParameter stateName = new SqlParameter();
stateName.SqlDbType = SqlDbType.NVarChar;
stateName.Direction = ParameterDirection.Input;
stateName.ParameterName = "#Name";
stateName.Size = 50;
Console.Write("Enter state name: ");
stateName.Value = Console.ReadLine();
cmd.Parameters.Add(stateName);
cmd.CommandText = #"IF EXISTS (SELECT name FROM sysobjects WHERE name='FindState' AND type='P') DROP PROCEDURE FindState";
cmd.ExecuteNonQuery();
cmd.CommandText = #"CREATE PROCEDURE FindState
#Name nvarchar(50)
AS
SELECT IDState FROM State WHERE Name=#Name";
cmd.ExecuteNonQuery();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "FindState";
sdr = cmd.ExecuteReader();
if (sdr.HasRows)
{
while (sdr.Read())
{
Console.WriteLine("ID state " + stateName.Value + " is " + sdr[0]);
}
}
else
{
Console.WriteLine("No such state exists");
}
sdr.Close();

try this:
SqlParameter stateName = new SqlParameter();
stateName.SqlDbType = SqlDbType.NVarChar;
stateName.Direction = ParameterDirection.Input;
stateName.ParameterName = "#Name";
stateName.Size = 50;
Console.Write("Enter state name: ");
stateName.Value = Console.ReadLine();
cmd.Parameters.Add(stateName);
cmd.CommandText = "IF EXISTS (SELECT name FROM sysobjects WHERE name='FindState' AND type='P') DROP PROCEDURE FindState";
cmd.ExecuteNonQuery();
cmd.CommandText = "CREATE PROCEDURE FindState
#Name nvarchar(50)
AS
BEGIN
SELECT IDState FROM State WHERE Name=#Name";
END
cmd.CommandType = CommandType.StoredProcedure;
cmd.ExecuteNonQuery();
cmd.CommandText = "FindState";
sdr = cmd.ExecuteReader();
if (sdr.HasRows)
{
while (sdr.Read())
{
Console.WriteLine("ID state " + stateName.Value + " is " + sdr[0]);
}
}
else
{
Console.WriteLine("No such state exists");
}
sdr.Close();

Answer 2

I figured out what the problem was.
The parameter was added to the SqlCommand before creating the procedure.
I moved this line down and now it works
cmd.CommandText = #"CREATE PROCEDURE FindState #Name nvarchar(50) AS SELECT IDState FROM State WHERE Name=#Name";
cmd.ExecuteNonQuery();
cmd.CommandType = CommandType.StoredProcedure;
cmd.CommandText = "FindState";
cmd.Parameters.Add(stateName);
sdr = cmd.ExecuteReader();
