Question

使用下面的电子邮件功能时，出现错误信息

“ NEIQC.Models.Common.Email”的类型初始值设定项引发了异常。

功能代码在下面

public static void SendMail(string Username, string MailContent)
    {
        string error = string.Empty;
        string ToEmail = string.Empty;

        ToEmail = Username + "@ril.com";

        EmailService.Service ObjService = new EmailService.Service();
        ObjService.SendMail(ConfigurationManager.AppSettings["FromMailId"].ToString(), ToEmail, "", "", "Newly Added Vendor Information", MailContent, true, Convert.ToString(ConfigurationManager.AppSettings["SMTPServerAddress"]), out error);
    }

我要通过下面提到的代码来完成此功能。

strMailContent = Get_Email_Content(strVendorName, strVendorCode, strValidFrom, strValidTo, strCreatedBy);                

 Email.SendMail(strCreatedBy, strMailContent);

我不知道为什么会出现此错误。请帮助

更新

public class Email
{
    #region Variable Declarations
    UserProviderClient ObjUMS = new UserProviderClient();

    //string strReturnMessage = "";
    string strAppURL = ConfigurationManager.AppSettings["APPURL"].ToString();
    int GroupId = Int32.Parse(ConfigurationManager.AppSettings["GroupID"]);
    static string staticFromAddress = ConfigurationManager.AppSettings["From"].ToString();
    string strError = "";
    #endregion

    public static void SendMail(string Username, string MailContent)
    {
        string error = string.Empty;
        string ToEmail = string.Empty;

        ToEmail = Username + "@ril.com";

        EmailService.Service ObjService = new EmailService.Service();
        ObjService.SendMail(ConfigurationManager.AppSettings["FromMailId"].ToString(), ToEmail, "Jyotirmoy.Mohanty@ril.com", "", "Newly Added Vendor Information", MailContent, true, Convert.ToString(ConfigurationManager.AppSettings["SMTPServerAddress"]), out error);
    }
}

我怀疑From设置没有很好地填充到应用程序配置文件中，因为这是唯一可能导致您显示的代码中出现type initialization error + NullPointerException的情况。 / p>

引发异常的代码部分将是：

  static string staticFromAddress = ConfigurationManager.AppSettings["From"].ToString();

在这种情况下，错误出在web.config

  <appSettings>
    <add key="From" value="somehing"/> <!-- Missing a line like this -->
  </appSettings>
