推荐答案

public void ReadHtmlFile(string htmlFilePath)
        {
            string htmlText = string.Empty;
            try
            {
                using (StreamReader template = new StreamReader(htmlFilePath))
                {
                    htmlText = ConvertHtmlToString(template, false);
                    template.Close();
                }                
            }
            catch(Exception E)
            {
               
            }            
        }
		
public string ConvertHtmlToString(TextReader streamToRead, bool isHtml)
        {
            StringBuilder body = new StringBuilder();
            StringBuilder nextTag = new StringBuilder();
            bool inTag = false;
            char nextCharacter = char.MinValue;
            char tagStart = '

';

while（streamToRead.Peek（）> = 0）
{
nextCharacter = Convert.ToChar（streamToRead.Peek（））;
if（nextCharacter.Equals（tagStart））inTag =！inTag;

if（inTag）
{
nextTag.Append（Convert.ToChar（streamToRead.Read（）））;
if（nextTag.Length> = 50）
{
body.Append（nextTag.ToString（））;
nextTag.Length = 0;
inTag = false;
}
}
else if（nextTag.Length> 0）
{
if（nextCharacter.Equals（tagStart））nextTag.Append（Convert.ToChar（ streamToRead.Read（）））;
body.Append（ReplaceHtmlValues（nextTag.ToString（），isHtml））;
nextTag.Length = 0;
}
其他
{
body.Append（Convert.ToChar（streamToRead.Read（）））;
}
}

返回body.ToString（）;
}

private string ReplaceHtmlValues（string tag，bool isHtml）
{
string returnValue = string.Empty;
tag = tag.Trim（）;

switch（tag）
{
case

'; while (streamToRead.Peek() >= 0) { nextCharacter = Convert.ToChar(streamToRead.Peek()); if (nextCharacter.Equals(tagStart)) inTag = !inTag; if (inTag) { nextTag.Append(Convert.ToChar(streamToRead.Read())); if (nextTag.Length >= 50) { body.Append(nextTag.ToString()); nextTag.Length = 0; inTag = false; } } else if (nextTag.Length > 0) { if (nextCharacter.Equals(tagStart)) nextTag.Append(Convert.ToChar(streamToRead.Read())); body.Append(ReplaceHtmlValues(nextTag.ToString(), isHtml)); nextTag.Length = 0; } else { body.Append(Convert.ToChar(streamToRead.Read())); } } return body.ToString(); } private string ReplaceHtmlValues(string tag, bool isHtml) { string returnValue = string.Empty; tag = tag.Trim(); switch (tag) { case "
