从类对象填充Datagridview [英] Populate Datagridview from class objects

问题描述

大家好，

我正在尝试填充Datagridview表单类对象

请参阅下面的示例代码



代码：

Hi All,
I am trying to populate Datagridview form class objects
Please see the sample code below

Code:

public class Customer
{
  public string FirstName { get; set;}
  public string LastName { get; set;}
  public Address mAddress { get; set;}
}

public class Address
{
  public string Street { get; set;}
  public string PostalCode { get; set;}
  public string City { get; set;}
}


public List<customer>  SelectCustomer()
{
       List<customer>  CustomerList =  new    List<customer>  ();
       
  while(dr.Read())
     {
  Customer  mCustomer =new Customer();
  mAddress= new  Address();
  mCustomer.FirstName= dr["FirstName"].ToString();
  mCustomer.FirstName= dr["LastName"].ToString();
  mAddress.Street= dr["Street"].ToString();
  mAddress. PostalCode = dr["PostalCode"].ToString();
  mCustomer. mAddress= mAddress;

CustomerList.Add(mCustomer);
     }
   
       return CustomerList;
}

我使用List< customer>绑定Datagridview ，

它显示客户数据，但在地址栏中它只显示对象引用或没有数据。我已将data属性更改为mAddress。街道仍然没有显示它的价值。



将提前感谢任何帮助。

I have bind the Datagridview using List<customer> ,
It shows customer data but in the address column it only shows object reference or no data. I have changed the data property to mAddress. Street and still it does not show the value in it.

Will appreciate any help thanks in advance.
