byte[] source; byte[] dest; int srcOffset = 0; int dstOffset = 0; int count = 10; System.Buffer.BlockCopy(source, srcOffset, dest, dstOffset, count);2.string转字节数组
byte[] inputByte = System.Text.Encoding.Unicode.GetBytes(text);byte[] inputByte = System.Text.Encoding.ASCII.GetBytes(text);
3.字节数组转string
string str= System.Text.Encoding.UTF8.GetString(bytes);
4.windows换行符
Environment.NewLine
5.string转int
string str = "100"; int a = System.Int32.Parse(str);
6.判断Enter键是否按下
