我正在通过Coded UI（手动）编写数据驱动测试。我想从excel文件（Data.xlsx）获取数据。它将从xls表中获取数据并逐个放入Gridview。
例如：文件路径（控件类型：行）将从xls工作表(C:\Users\XXXXX\Desktop\malware\mal.txt)获取数据。我正在使用这种方法，但无法做到。任何人都可以提供帮助。??
string strFilePath = "C:\\Eclipse\\Checklist.xls";
string strConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;" + "Data Source=" + strFilePath + "; Jet OLEDB:Engine Type=5;" + "Extended Properties=Excel 8.0;";
OleDbConnection cnCSV = new OleDbConnection(strConnectionString);
cnCSV.Open();
OleDbDataAdapter daCSV = new OleDbDataAdapter();

关于这个主题有很多问题和答案，但这是一个快速回顾：T
这里有两种访问数据的方法：数据源或手动创建数据类
如何使用数据源可在此处找到：http://msdn.microsoft.com/en-us/library/ee624082.aspx 或者在这里：https://stackoverflow.com/questions/24114537/data-driven-testing-using-excel-file-saved-inside-the-project
另一种方法是创建一个数据类来进行数据访问： 见Coded UI driving test from multiple excel files
使用Microsoft.Office.Interop.Excel;
打开Excel实例：
private Microsoft.Office.Interop.Excel.Application excel;
...
excel = new Microsoft.Office.Interop.Excel.Application();
要打开特定的工作簿：
private Workbook workbook;
....
workbook = excel.Workbooks.Open(@"\\C\Data\YourDriver.xlsx");
获取特定工作表：
Worksheet worksheet = workbook.Worksheets["YourTestCaseWorkSheet"];
将Cell A2作为字符串
Range a2 = worksheet.get_Range("A2");
return a2.Text;
要杀死你的任务：
/// <summary>
/// Quits the excel process
/// </summary>
public void Quit()
{
Marshal.ReleaseComObject(this.worksheet);
Marshal.ReleaseComObject(this.workbook);
this.excel.Quit();
this.excel = null;
}
