Selenium C＃从Excel读取数据以进行数据驱动测试时出错

Question

我试图通过从Excel文件加载客户端代码到登录并执行其他操作来执行数据驱动测试。我正在尝试为client_code列中的所有客户端迭代我的测试。我只需要读取client_code列并获取数据以与这些客户端重复相同的测试。当我在代码下面运行时，我得到Null值

任何帮助都将非常感谢谢谢。

我正在使用ExcelDataReader v3.4.0，ExcelDataReader.DataSet v3.4.0，selenium Webdriver v3.11.0

我的Excel表格如下所示。

client_code		client_name
11111			Client1
22222			Client2
33333			Client3
44444			Client4
55555			Client5

这是我的代码：

ExcelUtil.cs

using ExcelDataReader;
using System;
using System.Collections.Generic;
using System.Data;
using System.IO;
using System.Linq;
using System.Runtime.Remoting.Messaging;
using System.Text;
using System.Threading.Tasks;


namespace MyDemoAutomation
    {
    public class ExcelUtil
        {
        public DataTable ExcelToDatable(string fileName)
            {
            // open file and returns as stream
            FileStream stream = File.Open(fileName, FileMode.Open, FileAccess.Read);
            // create openXmlReader via ExcelReaderFactory
            IExcelDataReader excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
            //Set the first row as column name
          var result1 = excelReader.AsDataSet(new ExcelDataSetConfiguration()
                {
                ConfigureDataTable = (_) => new ExcelDataTableConfiguration()
                    {
                    UseHeaderRow = true
                    }
                });
     
            // Return as dataset
            DataSet result = excelReader.AsDataSet();
            // Get all tables
            DataTableCollection table = result.Tables;
            // Store in Database
            DataTable resultTable = table["Sheet1"];
            // return
            return resultTable;

            }

        List<DataCollection> dataCol = new List<DataCollection>();
        public void PopulateInCollection(string fileName)
            {

            DataTable table = ExcelToDatable(fileName);
            for (int row = 1; row <= table.Rows.Count; row++)
                {

                for (int col = 0; col < table.Columns.Count; col++)
                    {

                    DataCollection dtTable = new DataCollection()
                        {

                        rowNumber = row,
                        colName = table.Columns[col].ColumnName,
                        colValue = table.Rows[row - 1][col].ToString()
                        };
                    dataCol.Add(dtTable);

                    }
                }
            }

        public string ReadData(int rowNumber, string columnName)
            {
            try
                {
                // Retriving data using LINQ to reduce much of iterations
                string data = (from colData in dataCol
                               where colData.colName == columnName && colData.rowNumber == rowNumber
                               select colData.colValue).SingleOrDefault();

                return data.ToString();
                }
            catch (Exception e)
                {
                return null;
                }
            }

        internal class DataCollection
            {
            public int rowNumber { get; internal set; }
            public string colName { get; internal set; }
            public string colValue { get; internal set; }
            }
        }
    }

测试类：

	[Test]
        public void DataDrivenTest_FromExcel()
            {

			Driver = new ChromeDriver();
			
            ExcelUtil util = new ExcelUtil();
            util.PopulateInCollection(@"C:danAutomationTestTestData	est.xlsx");

			Driver.FindElement(By.Id("contentPlaceholder_txtClientCode")).SendKeys(util.ReadData(i));
			
			Driver.FindElement(By.XPath("//*[@id='btnLogin']")).Click();
			Driver.FindElement(By.XPath("//*[@id='tabContent0']/table/tbody/tr[2]/td[1]")).Click();
			Driver.FindElement(By.Id("contentPlaceholder_txtcloseButton")).Click();
			
			Driver.Quit

            }
