对象引用未设置为对象c#代码的实例
我一直在玩这个代码,但是, 对象引用未设置为对象的实例 一个是有记号的箭头。谁能看看我做错了什么?我只发布了相关代码 谢谢 错误在//我的错误在这里对象引用未设置为对象c#代码的实例,c#,object-reference,C#,Object Reference,我一直在玩这个代码,但是, 对象引用未设置为对象的实例 一个是有记号的箭头。谁能看看我做错了什么?我只发布了相关代码 谢谢 错误在//我的错误在这里 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using Sys

//将信息加载到数组中
而(counter假设我输入“test”并且在“”周围拆分它时没有空格,wordsplit数组中将有一个元素,在第二次迭代时,将没有其他元素,所以我猜您在那里会出错。您不认为有可能是kbbody[counterWord]是空的…堆栈跟踪中指示了哪一行?根据我对它的读取,我将它运行到一个列表框中..如果DataAgreement与@astander一致,那么从读取文件到使用它的值缺少检查索引会导致太多问题,您不是来自这里吗
