將UI表格數據寫入CSV文件

Question

C＃的新手並試圖從網站上的數據表中獲取數據並將其保存到csv文件中。到目前爲止，我已經設法將數據導入到csv文件中，但是每個記錄都附加到A列中的新單元格（在Excel中查看）。即..

A   B   C 
1 A_record1 
2 A_record2 
3 A_record3 
4 B_record1 
5 B_record2 
6 B_record3 

而我想的數據是在格式csv文件...

A   B   C 
1 A_record1 A_record2 A_record3 
2 B_record1 B_record2 B_record3 

的代碼我有填充CSV在第一個例子是.. 。

//divided xpath In three parts to pass Row_count and Col_count values. 
String firstPart = "//div[@id='lwDataGrid']/table/tbody/tr["; 
String secondPart = "]/td["; 
String thirdPart = "]"; 

//Row and Column counts 
int rowCount = driver.FindElements(By.XPath("//div[@id='lwDataGrid']/table/tbody/tr[*]")).Count - 3; 
int colCount = driver.FindElements(By.XPath("//div[@id='lwDataGrid']/table/tbody/tr[1]/td")).Count; 
System.Diagnostics.Debug.WriteLine(rowCount + ": This is the number of rows in the table"); 
System.Diagnostics.Debug.WriteLine(colCount + ": This is the number of columns in the table"); 

string path = @"C:\...\my.csv"; 

for (int j = 2; j <= colCount; j++) 
{ 
    //Used for loop for number of columns. 
    for (int i = 4; i <= rowCount; i++) 
    { 
     //Prepared final xpath of specific cell as per values of i and j. 
     String finalXpath = firstPart + i + secondPart + j + thirdPart; 
     //Will retrieve value from located cell and print It. 
     String tableData = driver.FindElement(By.XPath(finalXpath)).Text; 
     using (StreamWriter sw = File.AppendText(path)) 
     { 
      sw.WriteLine(tableData); 
     } 
    } 
} 

的最終目標是到這個CSV比較另一個「期望的結果」 CSV檢查，在UI表中的數據如預期。如果有比比較兩個文件更有效的方法，即使用數組來比較結果csv，我願意提供建議。

任何幫助將不勝感激。

從改變你的代碼 -

for (int j = 2; j <= colCount; j++) 
{ 
    //Used for loop for number of columns. 
    for (int i = 4; i <= rowCount; i++) 
    { 
     //Prepared final xpath of specific cell as per values of i and j. 
     String finalXpath = firstPart + i + secondPart + j + thirdPart; 
     //Will retrieve value from located cell and print It. 
     String tableData = driver.FindElement(By.XPath(finalXpath)).Text; 
     using (StreamWriter sw = File.AppendText(path)) 
     { 
      sw.WriteLine(tableData); 
     } 
    } 
} 

下面可能會解決這個問題

for (int j = 2; j <= colCount; j++) 
     { 
      using (StreamWriter sw = File.AppendText(path)) 
      { 
       string line = string.Empty; 
       //Used for loop for number of columns. 
       for (int i = 4; i <= rowCount; i++) 
       { 
        //Prepared final xpath of specific cell as per values of i and j. 
        String finalXpath = firstPart + i + secondPart + j + thirdPart; 
        //Will retrieve value from located cell and print It. 
        String tableData = driver.FindElement(By.XPath(finalXpath)).Text; 
        line = line + string.Format("{0},",tableData); 
       } 
       sw.WriteLine(line); 
      } 
     }
