存取清单清单 [英] Access List of List

问题描述

我创建了一个列表列表来存储随机生成的数据，但是我的实现显示以下智能提示错误变量名称在当前上下文中不存在".我哪里出问题了?这是我的代码的必需部分.

I created a List of List to store randomly generated data however my implementations shows the following intellisense error "The variable name doesn't exist in current context". Where have I gone wrong? Here are the required portions of my code.

           List<List<string>> DataList = new List<List<string>>();
           //Some Code
            for (int i = 0; i < num; i++)
            {
                List<string> strVal = new List<string>();
                foreach (string someVal in SomeList)
                {                    
                    //Some Code
                    strVal.Add(data);
                }

                DataList.Add(strVal);
            }

            for (int i = 0; i < num; i++)
            {
                foreach (IList<string> name in DataList)
                {
                    foreach (string listVal in strVal) // Error Here
                    {
                        //Some Code
                    }                    
                }
            }

我哪里出问题了?谢谢.

Where have I gone wrong? Thanks.

推荐答案

  foreach (IList<string> name in DataList)
            {
                foreach (string listVal in strVal) // Error Here
                {
                    //So

应该是

  foreach (IList<string> name in DataList)
            {
                foreach (string listVal in name ) // Error Here
                {
                    //So
