{
Excel.Range rng = this.Application.get_Range("A"+count++,missing);
rng.Value2 = dr.ItemArray;
}
#endregion
}
4、删除Excel的sheet

{
#region the forth method:delete the worksheet
Application.DisplayAlerts = false;
((Excel.Worksheet)this.Application.ActiveWorkbook.Sheets[2]).Delete();
Application.DisplayAlerts = true;
Application.Quit();
#endregion
}
5、操作Excel的单元格

private void Sheet1_Startup(object sender, System.EventArgs e)
{
#region the fifth method:the excel named ranges
Microsoft.Office.Tools.Excel.NamedRange namedRange1 = Controls.AddNamedRange(this.Range["A1","A10"],"namedRange1");
Microsoft.Office.Tools.Excel.NamedRange namedRange2 = Controls.AddNamedRange(this.Range["A1",missing],"namedRange2");
namedRange1.Merge(false);
namedRange2.Merge(false);
namedRange1.BorderAround(missing, Excel.XlBorderWeight.xlHairline, Excel.XlColorIndex.xlColorIndexAutomatic, missing);
namedRange1.AutoFormat(Excel.XlRangeAutoFormat.xlRangeAutoFormat3DEffects1,true,false,true,false,true,true);
#endregion
}
6、单元格式限定

private void Sheet1_Startup(object sender, System.EventArgs e)
{
#region this sixth method:cell manipulation
Excel.Range rng = Globals.Sheet1.Range["B3", "B3"] as Excel.Range;
rng.Value2 = "123456";
rng.NumberFormat = "$#,###.0";
rng = rng.Cells[3, 3] as Excel.Range;
rng.Value2 = "new";
#endregion
}
7、单元格合并

private void Sheet1_Startup(object sender, System.EventArgs e)
{
#region the seventh method:working with unions
Excel.Range rngA = Globals.Sheet1.Range["a2", "B3"] as Excel.Range;
rngA.Value2 = "Mortgage";
Excel.Range rngB = Globals.Sheet1.Range["a5", "B6"] as Excel.Range;
rngB.Value2 = "Interest";
Excel.Range unionRange = Application.Union(rngA,rngB,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing,missing) as Excel.Range;
unionRange.Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);
#endregion
}
8、密码保护

private void Sheet1_Startup(object sender, System.EventArgs e)
{
#region the eighth method:workbook password protection
string password = this.Password;
this.Protect(password, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing, missing);
this.Unprotect(password);
#endregion
}
9、单元格事件触发

private void Sheet1_Startup(object sender, System.EventArgs e)
{
#region the ninth method:responding to events
Microsoft.Office.Tools.Excel.NamedRange namedRange1 = Globals.Sheet1.Controls.AddNamedRange(Globals.Sheet1.Range["A1",missing],"NamedRange");
namedRange1.Change+=new Microsoft.Office.Interop.Excel.DocEvents_ChangeEventHandler(namedRange1_Change);
#endregion
}
private void namedRange1_Change(Microsoft.Office.Interop.Excel.Range target)
{
if (!this.Application.CheckSpelling((string)target.Value2, null, true))
{
MessageBox.Show("拼写有误!");
}
}
