如何可以跳過使用C＃

Question

跨越在Excel多個行細胞所以我有一個for循環是這樣..：

for (int i = 12; i < 200; i++) 
{ 
    //Console.WriteLine(Convert.ToString(sheet01.Cells[12, 2].Value2)); 
    if (!(string.IsNullOrEmpty(sheet01.Cells[i, 2].Value2)) && sheet01.Cells[i, 2].Value2.Length == 4) 
    { 
     Console.WriteLine(sheet01.Name); 
     hcnNumber.Add(Convert.ToString(sheet01.Cells[i, 2].Value2)); 
    } 
} 

此代碼遇到錯誤每當細胞[I，2]當我跨越多個列。

如何跳過跨越多列的行行？

這樣的東西，如果row.length> 1

感謝

我想您的要求工作，我的本地系統上。如果我理解你的要求，你只需要顯示那些只有第一列有值的行，如果例如一行有10列，其中全部或多於1列包含數據，則需要跳過。我認爲它應該可以幫助你達到目標。 下面是循環並給出預期結果的代碼。

Excel.Application xlApp = new Excel.Application(); 
     Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:\Users\acn\Desktop\CopyofFinancialSample.xlsx"); 
     Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1]; 
     Excel.Range xlRange = xlWorksheet.UsedRange; 


     int rowCount = xlRange.Rows.Count; 
     int colCount = xlRange.Columns.Count; 

     for (int i = 1; i <= rowCount; i++) 
     { 
      int count = 0; 
      for (int j = 1; j <= colCount; j++) 
      { 

       //add useful things here! 
       if (j != 1) 
       { 
        if (xlRange.Cells[i, j] != null && xlRange.Cells[i, j].Value2 != null) 
        { 
         count++; 
        } 
       } 

      } 
      if (count > 0) 
      { 

      } 
      else 
      { 
       if (xlRange.Cells[i, 1] != null && xlRange.Cells[i, 1].Value2 != null) 
        Console.WriteLine(xlRange.Cells[i, 1].Value2.ToString() + "\t"); 
      } 
     } 

如果你需要完整的控制檯程序來測試REQ，請在下面找到

class Program 
{ 
    static void Main(string[] args) 

    { 

     //Create COM Objects. Create a COM object for everything that is referenced 
     Excel.Application xlApp = new Excel.Application(); 
     Excel.Workbook xlWorkbook = xlApp.Workbooks.Open(@"C:\Users\acn\Desktop\CopyofFinancialSample.xlsx"); 
     Excel._Worksheet xlWorksheet = xlWorkbook.Sheets[1]; 
     Excel.Range xlRange = xlWorksheet.UsedRange; 


     int rowCount = xlRange.Rows.Count; 
     int colCount = xlRange.Columns.Count; 

     for (int i = 1; i <= rowCount; i++) 
     { 
      int count = 0; 
      for (int j = 1; j <= colCount; j++) 
      { 

       //add useful things here! 
       if (j != 1) 
       { 
        if (xlRange.Cells[i, j] != null && xlRange.Cells[i, j].Value2 != null) 
        { 
         count++; 
        } 
       } 

      } 
      if (count > 0) 
      { 

      } 
      else 
      { 
       if (xlRange.Cells[i, 1] != null && xlRange.Cells[i, 1].Value2 != null) 
        Console.WriteLine(xlRange.Cells[i, 1].Value2.ToString() + "\t"); 
      } 
     } 
     //cleanup 
     GC.Collect(); 
     GC.WaitForPendingFinalizers(); 

     //rule of thumb for releasing com objects: 
     // never use two dots, all COM objects must be referenced and released individually 
     // ex: [somthing].[something].[something] is bad 

     //release com objects to fully kill excel process from running in the background 
     Marshal.ReleaseComObject(xlRange); 
     Marshal.ReleaseComObject(xlWorksheet); 

     //close and release 
     xlWorkbook.Close(); 
     Marshal.ReleaseComObject(xlWorkbook); 

     //quit and release 
     xlApp.Quit(); 
     Marshal.ReleaseComObject(xlApp); 
     Console.ReadLine(); 

    } 
}
