我就废话不多说了，大家还是直接看代码吧~
string PrintName = cmbPrinter.SelectedIndex.ToString();
PrintName = cmbPrinter.SelectedItem.ToString(); //
if (cmbPrinter.SelectedIndex != 0)
{
}
string PrintName = "";
PrintName = cmbPrinter.SelectedItem.ToString(); //"Gprinter GP-1124T0"
var ss0 = cmbPrinter.Text; //Gprinter GP-1124T0"
var ss = cmbPrinter.SelectedIndex.ToString(); // 0
//循环下拉框
string ptr = dals.SelectContentByID(1); //查询系统表中 打印机名称
for (int i = 0; i < cmbPrinter.Items.Count; i++)
{
if (cmbPrinter.Items[i].ToString() == ptr)
{
cmbPrinter.SelectedIndex = i;
break;
}
}
补充：C# wpf 获取combobox选中的值
获取当前所显示的值
combobox.Text;
获取SelectionChanged后选中的值
combobox.SelectedItem;
