如何在asp.net中获取文件上传控件的完整路径?

我正在使用文件上传控件在我的项目中使用asp.net 2.0，因此浏览驱动器并选择文件，例如path(D:\ user doc new 2011 \ Montana \ MT_SUTA_2010-2011.html)强> 但是在我的代码中看到错误是找不到文件路径是 (D:\ Paymycheck \ OnlineTaxUserDocumentation-1 \ TaxesDocument \ MT_SUTA_2010-2011.2011)实际上是应用程序路径，仅使用我的代码获取文件名

i am using asp.net 2.0 in my project using file upload control , so browse the drive and select the file like path(D:\user doc new 2011\Montana\MT_SUTA_2010-2011.html) but in my code seeing error is could not find the file path is (D:\Paymycheck\OnlineTaxUserDocumentation-1\TaxesDocument\MT_SUTA_2010-2011.html) actually it is application path and take the filename only my code is

if (FileUpload.HasFile)
        {
string filepath = Server.MapPath(FileUpload.FileName);
string strHTML = File.ReadAllText(filepath);
                System.Text.ASCIIEncoding encoding = new System.Text.ASCIIEncoding();
                byte[] file1 = encoding.GetBytes(strHTML);
                int len = file1.Length;
                byte[] file = new byte[len]; 

                docs.TaxAuthorityName = ddlTaxAuthority.SelectedItem.Text;
                docs.TaxTypeID = ddlTaxType.SelectedValue;
                docs.TaxTypeDesc = ddlTaxType.SelectedItem.Text;
                docs.EffectiveDate = Convert.ToDateTime(txtEffectiveDate.Text);

                docs.FileName = f1;
                if (ddlTaxAuthority.SelectedValue == "FD")
                {

                    docs.Add(strHTML, file1);
                }
}

此行中发生错误

string strHTML = File.ReadAllText(filepath);

我也可以尝试这样

string FolderToSearch = System.IO.Directory.GetParent(FileUpload.PostedFile.FileName).ToString();
string f = Path.GetDirectoryName(FileUpload.PostedFile.FileName);
string f1 = FileUpload.FileName;
                 string filepath = System.IO.Path.GetFullPath(FileUpload.PostedFile.FileName);
 string strFilePath = FileUpload.PostedFile.FileName;
string file1234 = System.IO.Path.GetFullPath(FileUpload.PostedFile.FileName);
string filepath = FileUpload.PostedFile.FileName;

那么如何获取文件的总路径驱动器 请帮助我任何人
