字符串整数转换？编译器错误消息：CS1502

Question

localhost.WebService x = new localhost.WebService();סרוויס 

if (Session["UserName"]!= null) 
{ 
    string UserName = Session["UserName "].ToString(); 
    HiddenField HiddenField1 = (HiddenField)e.Item.FindControl("HiddenField1"); 
    Image y = (Image)e.Item.FindControl("Image1"); 

    int Price = int.Parse(HiddenField1.Value); 
    int BuyerID = int.Parse(HiddenField1.Value); 
    x.AddOrder(BuyerID, Price, y.ImageUrl); 
} 
else 
    Response.Redirect("Registration.aspx"); 

[WebMethod] 
public void AddOrder(int BuyerID, int Price, int ArtPiece) 
{ 
    OleDbDataAdapter x = new OleDbDataAdapter("AddOrder", objConn); 
    x.SelectCommand.CommandType = CommandType.StoredProcedure; 

    OleDbParameter objParam = new OleDbParameter("@BuyerID", OleDbType.Char); 
    objParam.Value = BuyerID; 
    x.SelectCommand.Parameters.Add(objParam); 

    objParam = new OleDbParameter("@Price", OleDbType.Char); 
    objParam.Value = Price; 
    x.SelectCommand.Parameters.Add(objParam); 

    objParam = new OleDbParameter("@ArtPiece", OleDbType.Char); 
    objParam.Value = ArtPiece; 
    x.SelectCommand.Parameters.Add(objParam); 

    x.SelectCommand.ExecuteNonQuery(); 
} 

值ArtPiece是Access文件中的字符串类型。在此行上

x.AddOrder(BuyerID, Price, y.ImageUrl); 

y.ImageUrl显示错误。我能做些什么来解决它？

您已经声明ArtPiece为INT：

public void AddOrder(int BuyerID, int Price, int ArtPiece) 

我想这应该是：

public void AddOrder(int BuyerID, int Price, string ArtPiece)
