我这段代码在运行的时候就出错,认为数组大小定义不对,而我修改后虽然能运行,总只能读取正确一个2位的16进制数?
private void Read_Click(object sender, EventArgs e)
{
int x = this.serialPort1.BytesToRead;
if (this.serialPort1.BytesToRead > this.serialPort1.ReceivedBytesThreshold)
{
byte[] liu1 = new byte[x];
this.serialPort1.Read(liu1, 0, x);

//StringBuilder sb = new StringBuilder();

this.textBoxGet.Text += liu1[this.serialPort1.BytesToRead].ToString();(这句如果改成下面:


this.textBoxGet.Text += liu1[x].ToString();运行程序则提示:索引超出了数组界限


请指点, 而且上面能运行的代码也只能读取到01-ff范围内的数.
