c＃ - 如何使用serialPort.ReadExisting（）比较字符串

Question

有没有办法比较声明为的字符串与从串口接收的数据，例如：

string hello = "hello";
string dataReceived = serialPort1.ReadExisting();  //the incoming data is "hello"
bool comparisonResult = hello.Equals(dataReceived, StringComparison.Ordinal);

if(comparisonResult == true)
{
    //do something
}

提前致谢！

Answer 1

是的，有办法

if (serialPort1.ReadExisting() == "hello")
{
  // do something
}

Answer 2

编辑：找出它为什么不起作用，我需要的是文化敏感的比较

string hello = "hello";
string dataReceived = serialPort1.ReadExisting();  //incoming data is "hello"
int comparisonResult = String.Compare(hello, dataReceived, true);
//if comparisonResult is true, output is 0

if (comparisonResult == 0)
{
     //do something
}
