Answer 3

以我的经验来判断，这里并不是抛出你图片中那个错误的地方。因为这里似乎一个DateTime类型的数据都没有。
要不你多发点代码，要不你自己仔细检查一下是不是这里出错。

Answer 4

        private DataSet ds;
        private DataSet dsView;          
private void btnExlt_Click(object sender, System.EventArgs e)
{
this.Close();
} private void frmAddBook_Load(object sender, System.EventArgs e)
{
            AddSortDB ad = new AddSortDB();
            ds = ad.load();
            this.cboSort.DataSource = ds.Tables["bookSort"];
            this.cboSort.DisplayMember = ds.Tables["bookSort"].Columns["类别名称"].ToString();
    this.cboSort.SelectedIndex=0;
            AddBookDB ab = new AddBookDB();
            dsView = ab.load();
            this.dbgBook.DataSource = dsView;
            this.dbgBook.DataMember = "view_SortBooks";
        }
        public string sortName
        {
            get
            {
                return this.cboSort.SelectedItem.ToString();
            }
        }
        public object objAddBook
        {
            get
            {
                return this;
            }
        }
        public string Code
        {
            get
            {
                return this.txtCode.Text;
            }
        }
        public string bName
        {
            get
            {
                return this.txtBookName.Text;
            }
        }
        public string Author
        {
            get
            {
                return this.txtAuthor.Text;
            }
        }
        public string Company
        {
            get
            {
                return this.txtCompany.Text;
            }
        }
        public decimal Price
        {
            get
            {
                return Convert.ToDecimal(this.txtPrice.Text);
            }
        }
        public int Num
        {
            get
            {
                return Convert.ToInt32(this.txtNum.Text);
            }
        }        private void btnAdd_Click(object sender, EventArgs e)
        {
            AddBookDB ad = new AddBookDB();
            ad.addBooks(this);
            ad.load();
        }
}
}所有代码中都没有涉及到DateTime...昨天开始也是这问题,后来不知怎么就好了

Answer 5

不过如果你调试了是那一行转换Decimal的出错，你可以试着用
return Decimal.Parse(txtPrice.Text)；

Answer 6

晕，找个BLOG之类的地方上传嘛。
邮箱也可以[email protected]

Answer 7

return   Decimal.Parse(txtPrice.Text)； 
一样的错,试过了,正在发邮件,数据库是SqlServer2000

Answer 8

是
return   Convert.ToDecimal(this.txtPrice.Text); 
这句出错么？
你加个断点看下this.txtPrice.Text 的值  看是不是不能转成Decimal

Answer 9

 public   decimal   Price 
                { 
                        get 
                        { 
                                return   Convert.ToDecimal(this.txtPrice.Text.trim()); 
                        } 
                } 怀疑为空格!

Answer 10

 public   decimal   Price 
                { 
                        get 
                        { 
                                return   Convert.ToDecimal(this.txtPrice.Text.trim()); 
                        } 
                } h怀疑为空格!

Answer 11

语句是对的！估计是楼主在输入值的时候多加空格了！ 
  
          return       Convert.ToDecimal(this.txtPrice.Text.trim());
