SendBloodListInfos[i].BloodId = "1";//报错 未将对象引用设置到对象的实例

再顶 adsa

[发飙的程序员1号]

初级程序员的硬伤，调试出来错误，不知道怎么改，这也能算错，不过找不到对象这种事经常碰到，碰到多了就知道怎么处理了

SendBloodListInfos[i]为null

[coliby]

偌大个CSDN都没有解决我的问题，还是我自己解决的 办法：HisService.SendBloodListInfo[] SendBloodListInfos = new HisService.SendBloodListInfo[gSendBloodListInfo.Length];声明类对象数组时候需要对数组中的每个对象进行初始化

for (int i = 0; i < gSendBloodListInfo.Length; i++)
                {
                    SendBloodListInfos[i] = new HisService.SendBloodListInfo();
                }

看你的代码写法，就知道你不调试。你既然无法跟人家说出具体的那一条语句抛出异常，你既然不调试、靠求人，那么只能个人也与开发。在一个正规的软件公司，这样不会vs调试的程序员是进不去的。

[以专业开发人员为伍]

如果你在一个正规软件公司里，你请技术经理给你看一下，人家一来就要操作你vs调试器，查看断点处的变量信息，甚至调用堆栈里深层入口的环境变量信息。 而你呢？扔给人家一个 errorMessage 字符串，这就是你提出这个帖子的方式。这个方式说明丧失了调试能力，所以没人解决你的问题啊。
