从数据库

Question

返回多行我使用下面的方法在Web服务返回一组数据 -

int T = 0; 
res.rows = new users[1]; 
     int cnt = 0; 

     while (reader.Read()) 
     { 

      if (T == 0) 
      { 

       res.rows[T] = new users(); 

       res.rows[T].age = (String)reader["age"]; 
       res.rows[T].height = (String)reader["height"]; 

       T = T + 1; 

      } 
      cnt = cnt + 1;    
     } 

     return res; 

我当前已设计了这个返回一行数据，这里设置res.rows = new users[1];然后j==0然后带回第一行数据。

我的问题是我怎么能修改这个带回多个/所有的数据行？ 在此先感谢。

Answer 1

试图保持在你的代码会是这样的改变最小，

int T = 0; 
res.rows = new List<User>(); 
    int cnt = 0; 

    while (reader.Read()) 
    { 

     //if (T == 0) 
     { 
      User u =new users(); 
      res.rows.Add(u); 

      res.rows[T].age = (String)reader["age"]; 
      res.rows[T].height = (String)reader["height"]; 

      T = T + 1; 

     } 
     cnt = cnt + 1;    
    } 

    return res;

public class User 
{ 
    private string m_Age; 
    private string m_Height; 

    public User() { } 

    public string Age 
    { 
     get { return m_Age; } 
     set { m_Age = value; } 
    } 

    public string Height 
    { 
     get { return m_Height; } 
     set { m_Height = value; } 
    } 

}

var rows = new List<User>(); 
while (reader.Read()) 
{ 

    var row = new User(); 
    row.Age = reader["age"]; 
    row.Height = reader["height"]; 
    rows.Add(row); 
} 

res.rows = rows; //if the res.rows property is an array then you can change this line to res.rows = rows.ToArray(); 

return res;
