如何将文本框条目放入while循环？C#

Question

这基本上就是我想要做的.我想允许某人输入他们想要运行特定程序的次数.我无法弄清楚的是如何将数字10改为(textBox1.Text).如果您有更好的方法,请告诉我.我是编程新手.

int counter = 1;
while ( counter <= 10 )
{
    Process.Start("notepad.exe");
    counter = counter + 1;
}

这显示了如何获取用户提供的输入并将其安全地转换为整数(System.Int32)并在计数器中使用它.

int counter = 1;
int UserSuppliedNumber = 0;

// use Int32.TryParse, assuming the user may enter a non-integer value in the textbox.  
// Never trust user input.
if(System.Int32.TryParse(TextBox1.Text, out UserSuppliedNumber)
{
   while ( counter <= UserSuppliedNumber)
   {
       Process.Start("notepad.exe");
       counter = counter + 1;  // Could also be written as counter++ or counter += 1 to shorten the code
   }
}
else
{
   MessageBox.Show("Invalid number entered.  Please enter a valid integer (whole number).");
}
