不知怎么的,这似乎在几年前就奏效了;)还是我错过了什么?
会通知帮助thx。
else if (recStatus == 3)
{
((TextBox)rref[1]).Text = read;
//string readData = read;
string[] readData = read.Split(new Char[] { ',' });
//string[] readdata = read.Split(',');
txtType.Text = readData[0];
txtSerno.Text = readData[1]
txtFirmware.Text = readData[2] + "." + readData[3];
}
系统。此代码中的IndexOutOfRangeException表示readData的值小于4,
你可以通过知道元素的数量
string[] readData = read.Split(new Char[] { ',' });
MessageBox.Show(readData.Length.ToString()); //you will found it less then 4
我刚刚运行了您的示例,在控制台应用程序中没有出现错误(可能是因为您正在传递的文本,请放入调试器,查看((TextBox)rref[1]上的实际文本)。文本):
class Program
{
static void Main(string[] args)
{
string read = "A401,192,2,8" ;
string[] readData = read.Split(new Char[] { ',' });
//string[] readdata = read.Split(',');
string a = readData[0];
string b = readData[1] + "." + readData[2];
string c = readData[3];
Console.WriteLine(a + b + c);
}
}
结果:
A401192.28
