使用泛型类型'System.Collections.Generic.List'需要'1' [英] Using the generic type 'System.Collections.Generic.List' requires '1'

问题描述

public static List<T> GetDriveTemp()
       {
           List<T> retval = new List<T>();
           try
           {
               ManagementObjectSearcher searcher = new ManagementObjectSearcher("root\\WMI", "SELECT * FROM MSStorageDriver_ATAPISmartData");
               //loop through all the hard disks
               foreach (ManagementObject queryObj in searcher.Get())
               {
                   byte[] arrVendorSpecific = (byte[])queryObj.GetPropertyValue("VendorSpecific");
                   //Find the temperature attribute
                   int tempIndex = Array.IndexOf(arrVendorSpecific, TEMPERATURE_ATTRIBUTE);
                   retval.Add(arrVendorSpecific[tempIndex + 5]);
               }
           }
           catch (ManagementException err)
           {
               Console.WriteLine("An error occurred while querying for WMI data: " + err.Message);
           }
           return retval;
       }

在此代码中我收到此错误 使用泛型类型''System.Collections.Generic.List< t>''需要''1''

推荐答案

你正在尝试将 byte 插入到定义为 List< string> 的对象中。您还错过了方法定义中返回类型的类型规范。

You are trying to insert a byte into an object defined as a List<string>. You have also missed the type specification from the return type on your method definition.
