如何在我的linq查詢中返回數據數組作為返回類型？

Question

以下是我的課程。 類的返回類型應該是CpsResponse，但我不知道如何將類放在我的類返回類型中。 我對編程世界很陌生。

  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;
            }
        }
    }

我從db獲取值到對象'customerData'。 現在我想返回值，我的返回類型應該是CpsResponse。 我怎樣才能做到這一點？

var customerResult = (from a in customerData
                       select new CpsResponse {//what actually I should //write here I don’t know, Please help});

請只做那些需要的。

在不知道CpsResponse的定義的情況下，我們無法准確回答這個問題，但基本上它看起來像：

List<CpsResponse> myList = (from a in customerdata
  select new CpsResonse { id = a.CustomerIdentifier, email = a.emailField }).ToList()

您可以使用DB中所需的字段選擇new並CpsResponse的屬性。
