[問題] 計算機不會累加
double varOperand;
bool ResultComplete ;
private void button16_Click(object sender, EventArgs e)
{
textBox1.Text = "";
textBox2.Text = "";
varOperand = 0;
ResultComplete = true;
}
private void button1_Click(object sender, EventArgs e)
{
if (ResultComplete == true)
{
textBox1.Text = "";
ResultComplete = false;
}
textBox1.Text = textBox1.Text + "1";
}
button16是clear清除
button1就是數字1 以此類推
textBox1是輸入數字與輸出的地方
在button1 click那邊我看得懂如果textBox1是空白的話
ResultComplete的狀態是false
也因此可以得知不是空白的話就是true
但實在是不知道一開始要怎麼宣告ResultComplete阿!!!
要怎麼寫可以讓電腦知道如果textBox非空的話狀態會是true?
實在是困擾很久
拜託各位高手幫小弟解惑!!!!!!!!!
