如何阅读Unicode字符?像一个”
public static string Read(int length, string absolutePath)
{
StringBuilder resultAsString = new StringBuilder();
using (MemoryMappedFile memoryMappedFile = MemoryMappedFile.CreateFromFile(absolutePath))
using (MemoryMappedViewStream memoryMappedViewStream = memoryMappedFile.CreateViewStream(0, length))
{
for (int i = 0; i < length; i++)
{
int result = memoryMappedViewStream.ReadByte();
if (result == -1)
{
break;
}
char letter = (char)result;
resultAsString.Append(letter);
}
}
return resultAsString.ToString();
}
读取的
int
(结果)为195,而char
强制类型转换未提供预期的结果。 最佳答案
不确定是不是您要的,但是可以使用StreamReader
StreamReader sr = new StreamReader(stream, Encoding.Unicode);
