C# 远程服务器返回意外响应：（413）Wcf服务中的请求实体太大错误

在下面的代码中，我正在使用wcf服务上载文本文件或pdf文件，当我尝试上载图像文件时，它会引发错误“远程服务器返回意外响应：（413）请求实体太大”。请任何人帮助我解决此问题

File.aspx.cs

 public void FileUpload(string FilePath, string FolderName)
        {



                FileServiceClient fileTranz = new FileServiceClient();

                var fileContent = File.ReadAllBytes(FilePath);
                FileInfo info = new FileInfo(FilePath);
                string filename = info.Name.ToString();

                var fileDto = new FileDto
                {
                    FileName = filename,
                    FileSize = fileContent.Length,
                    Content = fileContent
                };



                string fileName = Path.GetFileName(FilePath);
                var response = fileTranz.ServicetaxFileUpload(fileDto, fileName, "Image", sFileTransKey, FolderName);
                if ((System.IO.File.Exists(FilePath)))
                {
                    System.IO.File.Delete(FilePath);
                }                         



        }

FileService.svc.cs

public bool ServicetaxFileUpload(FileDto fileDto, string sFileName, string sFileType, string sCallFrom, string FolderName)
        {
                if (sCallFrom != "ttdll")
                    return false;
var Uploadpath = ConfigurationManager.AppSettings["HoardServer"].ToString();
                    Uploadpath = Uploadpath.TrimEnd("\\".ToCharArray()) + "\\PaidESI\\" + sFileName;
                    var DirectoryName = Path.GetDirectoryName(Uploadpath);
                    DirectoryInfo dInfo = new DirectoryInfo(DirectoryName);
                    if (!dInfo.Exists)
                    {
                        dInfo.Create();
                    }

                    if (sFileType == "Image")
                    {
                        //if (!File.Exists(Uploadpath))
                        File.WriteAllBytes(Uploadpath , fileDto.Content);
                    }
                    else if (sFileType == "Xml")
                        File.WriteAllBytes(Uploadpath , fileDto.Content);
                    else
                        File.WriteAllBytes(Uploadpath , fileDto.Content);
                }
