C# 实现 php中的file_get_contents

/// <summary>
/// Will return the string contents of a
/// regular file or the contents of a
/// response from a URL
/// </summary>
/// <param name="fileName">The filename or URL</param>
/// <returns></returns>
protected string file_get_contents(string fileName)
{
string sContents = string.Empty;
if (fileName.ToLower().IndexOf("http:") > -1)
{ // URL
System.Net.WebClient wc = new System.Net.WebClient();
byte[] response = wc.DownloadData(fileName);
sContents = System.Text.Encoding.UTF8.GetString(response);//以utf8的编码格式返回，如果返回值有乱码应该是跟页面的编码格式不同，自行更换编码格式
}
else
{
// Regular Filename
System.IO.StreamReader sr = new System.IO.StreamReader(fileName);
sContents = sr.ReadToEnd();
sr.Close();
}
return sContents;
}
