我想加载在类文件中声明的项,当窗体加载时,任何人都可以给我一个主意

我的类文件代码如下

namespace ACHDAL
{
   public class TansactionCode
   {
    string[] strTransactionCodes ={"20","21","22","23","24","25","26","27","28","29","30","31","32","33","34",
        "35","36","37","38","39","41","42","43","44","46","47","48","49","51","52","53","54","55","56","80",
        "81","82","83","84","85","86"};

}
}

如果需要在此代码中执行任何操作,请通知我,当表单加载时,希望将所有这些内容加载到组合框中。

通过设置组合框 DataSource 财产 (see here for more details on what you can bind to them) .

要做到这一点,您需要首先公开列表,所以将其放入一个属性中。这是窗体在创建类的新实例后访问它的方式。

public string[] TransactionCodes
{
    get { return strTransactionCodes; }
    set { strTransactionCodes = value; }
}

然后在FormLoad事件上执行此操作

如

private void Form1_Load(object sender, EventArgs e)
{
    TansactionCode trans = new TansactionCode();    // Create new instance
    combobox.DataSource = trans.TransactionCodes;   // Access the list property
}

我不确定,但我认为Linq也会有帮助。检查 this 链接。您需要相应地修改:
