work24 通过本文主要向大家介绍了c#中文乱码,c#读取中文乱码,c#读取txt文件乱码,c#乱码,c#字符串乱码等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
本文实例讲述了C#读取中文文件出现乱码的解决方法。分享给大家供大家参考。具体分析如下：
先来看这段代码：
FileStream aFile = new FileStream(SingleFile,FileMode.Open);
StreamReader sr = new StreamReader(aFile,Encoding.GetEncoding("gb2312"),true);
string FileContent = sr.ReadToEnd();
aFile.Close();
ProcessData Pd = new ProcessData();
Pd.ProceData(FileContent);
</div>
StreamReader 使用3个参数 最后一个自动检测utf-8，中文大部分是gb2312，如果不是utf-8，就用gb2312
系统自带utf 检测 ，见如下：
private void DetectEncoding()
{
if (this.byteLen >= 2)
{
this._detectEncoding = false;
bool flag = false;
if ((this.byteBuffer[0] == 0xfe) && (this.byteBuffer[1] == 0xff))
{
this.encoding = new UnicodeEncoding(true, true);
this.CompressBuffer(2);
flag = true;
}
else if ((this.byteBuffer[0] == 0xff) && (this.byteBuffer[1] == 0xfe))
{
if (((this.byteLen < 4) || (this.byteBuffer[2] != 0)) || (this.byteBuffer[3] != 0))
{
this.encoding = new UnicodeEncoding(false, true);
this.CompressBuffer(2);
flag = true;
}
else
{
this.encoding = new UTF32Encoding(false, true);
this.CompressBuffer(4);
flag = true;
}
}
else if (((this.byteLen >= 3) && (this.byteBuffer[0] == 0xef)) && ((this.byteBuffer[1] == 0xbb) && (this.byteBuffer[2] == 0xbf)))
{
this.encoding = Encoding.UTF8;
this.CompressBuffer(3);
flag = true;
}
else if ((((this.byteLen >= 4) && (this.byteBuffer[0] == 0)) && ((this.byteBuffer[1] == 0) && (this.byteBuffer[2] == 0xfe))) && (this.byteBuffer[3] == 0xff))
{
this.encoding = new UTF32Encoding(true, true);
this.CompressBuffer(4);
flag = true;
}
else if (this.byteLen == 2)
{
this._detectEncoding = true;
}
if (flag)
{
this.decoder = this.encoding.GetDecoder();
this._maxCharsPerBuffer = this.encoding.GetMaxCharCount(this.byteBuffer.Length);
this.charBuffer = new char[this._maxCharsPerBuffer];
}
}
}
</div>
