这是刚撸的代码，新鲜热辣。作用嘛就是为了将"数据表"中A列的单位名称去重后放到碗里去(combobox控件)。闲话不讲，直接上代码：

using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Xml.Linq;
using Microsoft.Office.Tools.Excel;
using Microsoft.VisualStudio.Tools.Applications.Runtime;
using Excel = Microsoft.Office.Interop.Excel;
using Office = Microsoft.Office.Core;
namespace Test
{
public partial class Sheet1
{
private void Sheet1_Startup(object sender, System.EventArgs e)
{
Excel.Worksheet shD = Application.ActiveWorkbook.Worksheets["数据表"];
Excel.Range rnAll = shD.Range["A2:A" + Convert.ToString(shD.Range["A1"].End[Excel.XlDirection.xlDown].Row)];
Dictionary<String,Int32> dicName1 = new Dictionary<string,Int32>();
String valStr;
foreach (Excel.Range rn in rnAll)
{
valStr = Convert.ToString(rn.Value);
dicName1[valStr] = rn.Row;
}
Dictionary<string, Int32>.KeyCollection keyColl = dicName1.Keys;
foreach (string s in keyColl)
{
comboBox1.Items.Add(s);
}
}
private void Sheet1_Shutdown(object sender, System.EventArgs e)
{
}
#region VSTO 设计器生成的代码
/// <summary>
/// 设计器支持所需的方法 - 不要
/// 使用代码编辑器修改此方法的内容。
/// </summary>
private void InternalStartup()
{
this.Startup += new System.EventHandler(this.Sheet1_Startup);
this.Shutdown += new System.EventHandler(this.Sheet1_Shutdown);
}
#endregion
public EventHandler comboBox1_SelectedIndexChanged { get; set; }
public MouseEventHandler comboBox1_MouseClick { get; set; }
public Excel.DocEvents_ActivateEventHandler Sheet1_ActivateEvent { get; set; }
public Excel.DocEvents_ChangeEventHandler Sheet1_Change { get; set; }
}
}
