下面给出的是我的课程。类的返回类型应该是CpsResponse,但我不知道如何把东西放在我的类返回类型中。我对编程世界非常陌生。如何在我的linq查询中返回数据数组作为返回类型?
public class CpsResponse
{
private CustomerProfile[] customerProfileField;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("CustomerProfile")]
public CustomerProfile[] CustomerProfile
{
get
{
return this.customerProfileField;
}
set
{
this.customerProfileField = value;
}
}
}
/// <remarks/>
public class CustomerProfile
{
private CustomerIdentifier customerIdentifierField;
private string emailField;
private string titleField;
private string firstNameField;
/// <remarks/>
public CustomerIdentifier CustomerIdentifier
{
get
{
return this.customerIdentifierField;
}
set
{
this.customerIdentifierField = value;
}
}
/// <remarks/>
public string Email
{
get
{
return this.emailField;
}
set
{
this.emailField = value;
}
}
/// <remarks/>
public string Title
{
get
{
return this.titleField;
}
set
{
this.titleField = value;
}
}
/// <remarks/>
public string FirstName
{
get
{
return this.firstNameField;
}
set
{
this.firstNameField = value;
}
}
}
/// <remarks/>
public class CustomerIdentifier
{
private string uniqueCustomerIdentifierField;
private string versionField;
/// <remarks/>
public string UniqueCustomerIdentifier
{
get
{
return this.uniqueCustomerIdentifierField;
}
set
{
this.uniqueCustomerIdentifierField = value;
}
}
/// <remarks/>
public string Version
{
get
{
return this.versionField;
}
set
{
this.versionField = value;
}
}
}
我从数据库中获取值到对象'customerData'中。现在我想返回值,我的返回类型应该是CpsResponse。我怎样才能做到这一点?
var customerResult = (from a in customerData
select new CpsResponse {//what actually I should //write here I don’t know, Please help});
请做好必要的工作。
你应该看看所谓的“自动执行的属性”。它将显着减少你的代码,同时达到相同的结果。 http://msdn.microsoft.com/en-us/library/bb384054.aspx –
不错,您应该将属性初始化代码添加到构造函数中,除非您喜欢空引用异常。 – Maess
