Hola chicos… Estoy intentando crear una página para cargar productos usando WCF. En esto estoy usando la biblioteca de servicios.
Pero cuando hace clic en el botón Agregar, se muestra que el servidor remoto lanzó la excepción llamada
El servidor remoto devolvió una respuesta inesperada: (413) Entidad de solicitud demasiado grande.
Lo que realmente hice al publicar en esta publicación, ¿alguien puede ayudarme a solucionar este problema?
agregue producto.aspx.cs:
HTML
protected void btnAdd_Click(object sender, EventArgs e)
{
try
{
if (ImageUpload.FileName != "")
{
string path = Server.MapPath("~/images/");
string extension = Path.GetExtension(ImageUpload.PostedFile.FileName);
if (((extension == ".jpg") || ((extension == ".gif") || (extension == ".png"))))
{
FileStream fs = new FileStream(path+ImageUpload.PostedFile.FileName, FileMode.Open,FileAccess.Read);
BinaryReader br = new BinaryReader(fs);
byte[] image = br.ReadBytes((int)fs.Length);
// byte[] raw = new byte[fs.Length];
//fs.Read(raw, 0, Convert.ToInt32(fs.Length));
modeldetails.UploadPhoto = image;
modeldetails.Serviceno = txtServiceNo.Text;
modeldetails.price= long.Parse( txtPrice.Text);
modeldetails.Name=txtName.Text;
modeldetails.ManfacturedDate=DateTime.Parse(txtManfacDate.Text.ToString());
modeldetails.Manfac_Product_ID=Int32.Parse(ddlProctype.SelectedItem.Value);
bool rows = proxy.AddNewProduct(modeldetails);
if (rows)
{
string script = "<script>alert('Data Added Successfully')</script>";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Added", script);
}
else
{
string script = "<script>alert('Error Adding Data')</script>";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Error", script);
}
}
else
{
StatusLabel.Text = "Only Jpg,gif or Png files are permitted";
}
}
else
{
StatusLabel.Text = "Kindly Select a File.....";
}
}
catch (Exception e1)
{
}
}

Hola,
Está enviando una entidad muy grande o una lista grande de entidades al cliente.
Cómo resolverlo.
