I have a C# string "RIP-1234-STOP\\0\\0\\0\\b\\0\\0\\0???|B?Mp?\\0\\0\\0" returned from a call to a native driver.
How can I trim all characters from first null terminator '\\0\\ onwards. In this case, I just would like to have "RIP-1234-STOP".
Thanks.
Here is a method that should do the trick
string TrimFromZero(string input)
{
int index= input.IndexOf('\0');
if(index < 0)
return input;
return input.Substring(0,index);
}
Try this:
var input = "RIP-1234-STOP\0\0\0\b\0\0\0???|B?Mp?\0\0\0";
var firstNull = input.IndexOf('\0');
var output = input.Substring(0, firstNull);
or simply:
var output = input.Substring(0, input.IndexOf('\0'));
This works too:
var input = "RIP-1234-STOP\0\0\0\b\0\0\0???|B?Mp?\0\0\0";
var split = input.Split('\0');
var output = split[0];
Assert.AreEqual("RIP-1234-STOP", output);
