无法将类型“string”隐式转换为“int”。拜求!!!!谢谢!!!
我用C#做个很简单的倒计时,在textBox1中输入数据m,然后利用timer1控件,就m--倒计时啊。运行报错:无法将类型“string”隐式转换为“int”。所有代码都在下面了。大哥大姐教教我吧。谢谢。
 
int m;

private void textBox1_TextChanged(object sender, EventArgs e)
  {
  if(this.textBox1.Text != "")
  {
  m = this.textBox1.Text;
  }
  }

private void timer1_Tick(object sender, EventArgs e)
  {
   
  m--;
  this.label2.Text = m.ToString()+"秒";
  label2.Refresh();
  }

 private void button1_Click(object sender, EventArgs e)
  {
  this .timer1.Enabled =true;
  }

------解决方案--------------------
int.Parse
------解决方案--------------------
m = int.Parse(this.textBox1.Text);
------解决方案--------------------
C# code

private void textBox1_TextChanged(object sender, EventArgs e)
  {
  if(this.textBox1.Text != "")
  {
  [b]m = Convert.ToInt32(this.textBox1.Text);[/b]
  }
  }

private void timer1_Tick(object sender, EventArgs e)
  {
    
  m--;
  this.label2.Text = m.ToString()+"秒";
  label2.Refresh();
  }

 private void button1_Click(object sender, EventArgs e)
  {
  this .timer1.Enabled =true;
  }
