Linux .net核心字符串运算符不会以例外结果执行

SDK:.net核心3.1 环境：ubuntu 18/04

代码：

结果:

3
-1   -> not as expected
True
2
True
False   -> not as expected

你需要使用。读了这篇文章，你就会明白发生了什么

Console.WriteLine("abc\n".IndexOf("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".IndexOf("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".Contains("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".Split('\n').Length);
Console.WriteLine("abc\n".EndsWith("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".EndsWith("\n", StringComparison.OrdinalIgnoreCase));

此行为可能与EOL符号的不同处理有关，请查看此

Console.WriteLine("abc\n".IndexOf("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".IndexOf("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".Contains("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".Split('\n').Length);
Console.WriteLine("abc\n".EndsWith("\n", StringComparison.OrdinalIgnoreCase));
Console.WriteLine("abc\r\n".EndsWith("\n", StringComparison.OrdinalIgnoreCase));
