Excel工作表添加问题c#
本文关键字:问题 添加 工作 Excel | 更新日期: 2023-09-27 18:08:47
我遇到的问题是,每次从组合框中选择一个数字时,它正在创建一个新的工作表。我只想将变量仅添加到活动工作表中,而不是每次都创建工作表。如有任何帮助,不胜感激。
这样的东西可以工作吗?
var xl = new Excel.Application();
xl.Visible = true;
var wb = (Excel._Workbook)xl.ActiveWorkbook; //(xl.Workbooks.Add(Missing.Value));
var sheet = (Excel._Worksheet)wb.ActiveSheet;
//Generate Linear Guide Support in Solidworks
if (comboBox1.Text == "0")
{
sheet.Cells[6, 4] = "0"; //Cell Location[y-axis, x-axis]
}
if (comboBox2.Text == "AH")
{
sheet.Cells[6, 5] = "AH";
}
if(comboBox3.Text == "2")
{
sheet.Cells[6, 6] = "2";
}
把这段代码提出来,不要在每次选择时都调用它。你可以移动它,使它只执行一次。
// Available at the class level. single instance - Singleton pattern may be employed
// Check the correct datatype for ExcelSheet
ExcelSheet sheet;
void UpdateExcelSheet(int row, int col, string value)
{
if (sheet == null)
{
var xl = new Excel.Application();
xl.Visible = true;
var wb = (Excel._Workbook)(xl.Workbooks.Add(Missing.Value));
sheet = (Excel._Worksheet)wb.ActiveSheet;
}
sheet.Cells[row, col] = value;
}
void OnComboSelection()
{
int row, col;
string value;
if(comboBox5.Text == "1")
{
row = 6; col = 6; value = "1";
}
if (comboBox3.Text == "2")
{
row = 6; col = 8; value = "2";
}
UpdateExcelSheet(row, col, value);
}
