摘要:若要填充一个多单元格区域而又不是一次一个单元格地进行填充,可以将“Range”对象的“Value”属性设置为二维数组。同样,通过使用“Value”属性,可以一次检索多个单元格的值的二维数组…

8. 返回到 Form1 的设计视图并双击“Button2”。

9. 在代码窗口中,将以下代码private void button2_Click(object sender, System.EventArgs e)
{
}
  
替换为: private void button2_Click(object sender, System.EventArgs e)
    {
    Excel.Sheets objSheets;
    Excel._Worksheet objSheet;
    Excel.Range range;

try
    {
      try
      {
       //Get a reference to the first sheet of the workbook.
       objSheets = objBook.Worksheets;
       objSheet = (Excel._Worksheet)objSheets.get_Item(1);
      }

catch( Exception theException )
      {
       String errorMessage;
       errorMessage = "Can't find the Excel workbook.  Try clicking Button1 " +
        "to create an Excel workbook with data before running Button2.";
       MessageBox.Show( errorMessage, "Missing Workbook?");
       //You can't automate Excel if you can't find the data you created, so
       //leave the subroutine.
       return;
      }

//Get a range of data.
      range = objSheet.get_Range("A1", "E5");
      //Retrieve the data from the range.
      Object[,] saRet;
      saRet = (System.Object[,])range.get_Value( Missing.Value );
      //Determine the dimensions of the array.
      long iRows;
      long iCols;
      iRows = saRet.GetUpperBound(0);
      iCols = saRet.GetUpperBound(1);
      //Build a string that contains the data of the array.
      String valueString;
      valueString = "Array Data\n";

for (long rowCounter = 1; rowCounter <= iRows; rowCounter++)
      {
       for (long colCounter = 1; colCounter <= iCols; colCounter++)
       {
        //Write the next value into the string.
        valueString = String.Concat(valueString,
          saRet[rowCounter, colCounter].ToString() + ", ");
       }
       //Write in a new line.
       valueString = String.Concat(valueString, "\n");
      }
      //Report the value of the array.
      MessageBox.Show(valueString, "Array Values");
    }

catch( Exception theException )
    {
      String errorMessage;
      errorMessage = "Error: ";
      errorMessage = String.Concat( errorMessage, theException.Message );
      errorMessage = String.Concat( errorMessage, " Line: " );
      errorMessage = String.Concat( errorMessage, theException.Source );
      MessageBox.Show( errorMessage, "Error" );
    }
    }  
 
10. 滚动到代码窗口的顶部。将下面的代码行添加到“using”指令列表的末尾:using System.Reflection;
using Excel = Microsoft.Office.Interop.Excel;

对自动化客户端进行测试

1. 按 F5 可生成并运行示例程序。

2. 单击“Button1”。该程序将启动 Microsoft Excel 并打开一个新工作簿,而且第一个工作表的单元格 A1:E5 已填充了来自某个数组的数值数据。

3. 单击“Button2”。该程序将检索单元格 A1:E5 中的数据并将其填充到一个新的数组中,然后将结果显示在一个消息框中。

4. 选择“FillWithStrings”,然后单击“Button1”,以用字符串数据填充单元格 A1:E5。
