C#-为控制思想循环赋值
我有按数字顺序命名的控件。 我想使用loop为这些控件赋值。 下面的代码是我当前使用的方式C#-为控制思想循环赋值,c#,winforms,loops,controls,C#,Winforms,Loops,Controls,我有按数字顺序命名的控件。 我想使用loop为这些控件赋值。 下面的代码是我当前使用的方式 txtSalesInvoiceForm_Qty1.Text = (salesInvoice.ItemQty1 == 0) ? string.Empty : salesInvoice.ItemQty1.ToString(); txtSalesInvoiceForm_Qty2.Text = (salesInvoice.ItemQty2 == 0) ? string.Empty : salesInvoice.I

(txtSalesInvoiceForm_Qty + index.ToString()).Text = Value;
indexer++
}
使用一个数组而不是这么多的命名变量，只索引到数组中。使用一个数组而不是这么多的命名变量，只索引到数组中
Control parent = this.pnlParent; // this must be the immediate parent control
int index = 1;
foreach (SalesInvoiceItem item in salesInvoice.SalesInvoiceItems)
{
TextBox tb = parent.FindControl( "txtSalesInvoiceForm_Qty" + index++ ) as TextBox;
tb.Text = Value;
}
FindControl（）键是
FindControl（）
