我在组合框 selectedindex 上遇到问题。基本上,当我的文本框结果为 1 时,我想禁用 button1。但问题是当 button1 被禁用时,我选择了另一个选项,它不会重新启用。那么还有其他方法吗?下面只是显示编码的一部分。
double[,] arr;
public Form1()
{
arr = new double[3, 3];
for (int i = 0; i < 2; i++)
{
arr[0, 0] = 1;
arr[0, 1] = 0.79;
arr[0, 2] = 1.17;
arr[1, 0] = 1.26;
arr[1, 1] = 1;
arr[1, 2] = 1.08;
arr[2, 0] = 0.85;
arr[2, 1] = 0.93;
arr[2, 2] = 1;
}
void CreateArray()
{
if (comboBox1.SelectedIndex == -1 || comboBox2.SelectedIndex == -1)
return;
else if (comboBox1.SelectedIndex == 1 || comboBox2.SelectedIndex == 0)
{
button1.Enabled = false;
}
else if (comboBox1.SelectedIndex == 0 || comboBox2.SelectedIndex == 1)
{
button1.Enabled = false;
}
else if (comboBox1.SelectedIndex == 1 || comboBox2.SelectedIndex == 2)
{
button1.Enabled = false;
}
else
{
button1.Enabled = true;
}
