如何调用一个过程，如果过程没有参数

Question

create proc sp_dropdown

FROM table1 as r1

end

这上面的类是我的SP返回类型，

public class GetAllTableNames_Result 
    { 
     public string Name { get; set; } 
    } 

，我可以把这个像

public List<GetAllTableNames_Result> GetTableNames() 
    { 
     List<GetAllTableNames_Result> gatnr = new List<GetAllTableNames_Result>(); 
     SqlCommand cmd = new SqlCommand(
      "GetAllTableNames", _connection) {CommandType = CommandType.StoredProcedure}; 
     try 
     { 
      _connection.Open(); 
      SqlDataReader rdr = cmd.ExecuteReader(); 
      while (rdr.Read()) 
      { 

        //do something with data 
       gatnr.Add(new GetAllTableNames_Result() 
       { 
        Name = rdr[0].ToString() 
       }); 

      } 
      _connection.Close(); 

      return gatnr; 
     } 
     catch (Exception e) 
     { 
      Console.WriteLine(e); 
      throw; 
     } 
     finally 
     { 
      _connection.Close(); 
     } 

    } 

我相信你可以得到点
