If you want to use the StreamReader, here is the code I am using:如果您想使用 StreamReader,这是我正在使用的代码:
const int Buffer_Size = 100 * 1024;
WebRequest request = CreateWebRequest(uri);
WebResponse response = request.GetResponse();
result = GetPageHtml(response);
... ...
private string GetPageHtml(WebResponse response) {
char[] buffer = new char[Buffer_Size];
Stream responseStream = response.GetResponseStream();
using(StreamReader reader = new StreamReader(responseStream)) {
int index = 0;
int readByte = 0;
do {
readByte = reader.Read(buffer, index, 256);
index += readByte;
}
while (readByte != 0);
response.Close();
}
string result = new string(buffer);
result = result.TrimEnd(new char[] {'\0'});
return result;
}
