Question

我想在datagrid中显示数据如下：

FILE_NAME | FILE_EXTENSION | FILE_PATH
__________ | _______________ | ___________
____ AFile__ | _____ DLL ________ | _C：\ PROGRAMFILES \的Windows \ FileA.dll
____ BFile__ | _____ DLL ________ | _C：\ PROGRAMFILES \的Windows \ FileB.dll
_____ + ____ | _______ + _______ | __________ + ____
_____ + ____ | _______ + _______ | __________ + ____
_____ + ____ | _______ + _______ | __________ + ____
........等等

.csv文件中的数据存储为

Row1（AFile，.dll，C：\ ProgramFiles \ Windows \ AFile.exe）

Row2（BFile，.dll，C：\ ProgramFiles \ Windows \ AFile.exe）
  我不知道如何在datagrid中以上述方式显示数据，请帮帮我。

Answer 1

按顺序执行以下操作

1）使用某种方法（FileStream或其他）读取CSV文件的数据 2）使用字符串拆分功能分离CSV（您可以找到许多方法来读取csv文件）
3）解析并格式化每个字符串输出并创建类型List<File>的列表（类结构下面的Se）并填写列表中的项目
4）将List绑定到ItemSource属性中的DataGrid。

public class File
{
   public String FileName
   {
       get;
       set;
   }

   public string Filepath
   {
       get;
       set;
   }  

}

如果您不清楚任何步骤，请尝试使用Google搜索...大部分帮助您执行此操作的文献已经可用，下次还会形成发布您在提问时尝试的内容否则您的问题将被低估。
