Excel VBA常用代码VSTO版20150425

21-1 使用工作表的名称
this.Application.Worksheets["工作表2"].Activate();
21-2 使用工作的索引号
this.Application.Worksheets[2].Activate();
21-3 使用工作表的代码名称
MessageBox.Show(this.Application.ActiveSheet.CodeName);
21-4 用ActiveSheet属性引用活动工作表
this.Application.Worksheets[2].Select();
MessageBox.Show( );
22-1 选择工作表的方法
this.Application.Worksheets[2].Select();
this.Application.Worksheets[2].Activate();
23-1 使用For遍历工作表
int wkCount = this.Application.Worksheets.Count;
string s = string.Empty;
for (int i = 1; i <= wkCount; i++)
{
s = s + this.Application.Worksheets[i].Name + "\n";
}
MessageBox.Show("工作簿中含有以下工作表:" + "\n" + s);
23-2 使用ForEach语句
string s = string.Empty;
foreach (Excel.Worksheet wk in this.Application.Worksheets) {
s = s + + "\n";
}
MessageBox.Show("工作簿中含有以下工作表:" + "\n" + s);
24-1 在工作表中向下翻页
Excel.Sheets shs=Globals.ThisWorkbook.Worksheets; Excel.Worksheet wkThis = shs.Application.ActiveSheet; Excel.Worksheet wkNext;
int wkIndex = wkThis.Index;
int wkCount = shs.Count;
if (wkIndex < wkCount)
{
wkNext = (Excel.Worksheet)wkThis.Next;
wkNext.Select();
}
25-1 工作表的添加与删除
Excel.Sheets wksThis = this.Application.Worksheets;
Excel.Worksheet wsAdd = this.Application.Worksheets.Add(System.Type.Missing, wksThis[wksThis.Count]);
= "数据";
25-1 批量添加工作表
Excel.Sheets wksThis = this.Application.Worksheets;
Excel.Worksheet wksNew = null;
if (wksThis.Count <= 3)
{
for (int i = 1; i <= 10; i++)
{
wksNew = wksThis.Add(System.Type.Missing, wksThis[wksThis.Count]);
= "第" + i.ToString() + "个工作表";
}
}
26-1 禁止删除指定工作表
mandBarControl cmdCtl =mandBars[41].Controls[2];
可以找到删除按钮,但是无法禁止,也无法加载单击事件,非常奇怪.
而且在Office 2010里,也无法禁用某个按钮,但是整个菜单是可以的.
27-1 自动建立工作表目录
int i = this.Application.Worksheets.Count;
for (int n = 1; n <= i; n++)
{
this.Cells[n+1, 1].Value = this.Application.Worksheets[n].Name;
}
27-1 建立工作表链接
int m = this.Application.Worksheets.Count;
if (Target.Count == 1)
{
if (Target.Column==1)
{
if (Target.Row>1 && Target.Row<=(m+1))
{
this.Application.Sheets[Target.Value].Select();
}
}
}
28-1 工作表的深度隐藏
this.Application.Sheets[2].Visible = Excel.XlSheetVisibility.xlSheetVeryHidden;
29-1 防止更改工作表的名称
void ThisWorkbook_BeforeClose(ref bool Cancel)
{
if (this.Sheets[1].Name != "Excel Home")
{
this.Sheets[1].Name = "Excel Home";
}
this.Save();
}
30-1 工作表中一次插入多行
Excel.Range rng = this.Rows[3];
rng.Resize[3].Insert();
31-1 删除工作表中的空行
Excel.Range rng = edRange;
int rngEnd = this.Cells[rng.Rows.Count,rng.Columns.Count].End[Excel.XlDirection.xlUp].Row;
for (int i = rngEnd; i >=1; i++)
{
if (this.Application.WorksheetFunction.CountA(this.Rows[i]) == 0)
{
this.Rows[i].Delete();
}
}
32-1 删除工作表的重复行
int rngEnd = this.Range["A65535"].End[Excel.XlDirection.xlUp].Row;
for (int i = rngEnd; i>=1; i--)
{
if (this.Application.WorksheetFunction.CountIf(this.Columns[1], this.Cells[i, 1]) > 1)
{
this.Rows[i].Delete();
}
}
33-1 定位删除特定内容所在的行(删除A列中包含”Excel”字符的行this.Application.DisplayAlerts = false;
int rngEnd = this.Range["A65535"].End[Excel.XlDirection.xlUp].Row;
string str = "Excel.*";
for (int i = rngEnd; i >= 1; i--)
{
Excel.Range rng = this.Cells[i, 1];
if (Regex.IsMatch(rng.Text, str))
{
this.Rows[i].Delete();
}
}
注:需引用using System.Text.RegularExpressions;
34-1 判断是否选中整行
int i = this.Columns.Count;
Excel.Range rng = this.Application.Selection;
if (rng.Columns.Count == i)
{
MessageBox.Show("你选中了一整行");
}
else
{
MessageBox.Show("你没有选中了一整行");
}
35-1 限制工作表的滚动区域
this.ScrollArea = "B4:H12";
36-1 复制自动筛选后的数据区域
this.Application.Worksheets[2].Cells.Clear();
if (this.FilterMode)
{
this.AutoFilter.Range.SpecialCells(Excel.XlCellType.xlCellTypeVisible).Copy( this.Application.Worksheets[2].Cells[1, 1]);
}
37-1 使用高级筛选获得不重复记录
Excel.Range rngSheet2 = this.Application.Worksheets[2].Cells;
rngSheet2.Clear();
this.Range["A1"].CurrentRegion.AdvancedFilter(
Excel.XlFilterAction.xlFilterCopy,
System.Type.Missing,
this.Application.Worksheets[2].Cells[1, 1],
true);
38-1 工作表的保护与解除保护
this.Unprotect("12345");
this.Cells[1,1].Value=100;
this.Protect("12345");
39-1 奇偶页打印
int pg = this.PageSetup.Pages.Count;
for (int i = 1; i <= pg; i=i+2)
{
this.PrintOutEx(1, i);
}
40-1 使用工作簿的名称
string str = this.Application.Workbooks["工作簿的引用方法.xlsx"].Path;
MessageBox.Show(str);
40-3 使用ThisWorkbook
this.Application.ThisWorkbook.Close(false);
40-4 使用ActiveWorkbook
MessageBox.Show();
41-1 新建工作簿
Excel.Workbook Nowbook;
string[] shName = new string[4] { "余额", "单价", "数量", "金额" };
string[] arr = new string[12] { "01月", "02月", "03月", "04月", "05月", "06月", "07月", "08月", "09月", "10月", "11月", "12月" };
this.Application.SheetsInNewWorkbook = 4;
Nowbook = this.Application.Workbooks.Add();
for (int i = 1; i <= 4; i++)
{
Nowbook.Sheets[i].Name = shName[i - 1];
Nowbook.Sheets[i].Range["B1"].Resize[1, arr.Length] = arr;
Nowbook.Sheets[i].Range["B2"] = "品名";
}
Nowbook.SaveAs("C:\\" +"存货明细.xlsx");
Nowbook.Close(true);
42-1 打开指定的工作簿
int wkCount = this.Application.Workbooks.Count;
for (int i = 1; i <= wkCount; i++)
{
if (this.Application.Workbooks[i].Name == "123.xlsx")
{
MessageBox.Show("123工作簿已经打开");
}
}
this.Application.Workbooks.Open("C:\\" + "123.xlsx");。
