低级错误-DataView.Count属性。

低级错误-DataView.Count属性。

记录个自己的低级错误!!!!!!!!!!!!!!!!!

今天在对一个表进行删除，发现以下问题：

先附一段代码：（方便调试，加了些MessageBox.）
            string deleteID = this.costomerDataGrid[this.costomerDataGrid.CurrentRowIndex, 6].ToString();
            this.costomer_RecordTableAdapter.Fill(this.realEstatePDADataSet.Costomer_Record);
            MessageBox.Show("过滤前的dataView集合数："+this.dataView2.Count.ToString());
            this.dataView2.RowFilter = "客户编号 = '" +deleteID+ "'";
            //this.dataView1.Sort = "来访时间";
            MessageBox.Show("过滤条件：" + deleteID);
            MessageBox.Show("过滤后的dataView集合数："+this.dataView2.Count.ToString());
            this.costomer_RecordBindingSource.EndEdit();
            for (int i = 0; i < this.dataView2.Count; i++)
            {
                MessageBox.Show("删除第"+i+"条记录");
                this.costomer_RecordBindingSource.RemoveAt(i);
            }
            this.costomer_RecordTableAdapter.Update(this.realEstatePDADataSet.Costomer_Record);
            MessageBox.Show("删除成功!");

出现问题：表中的记录没被清除完全。仔细检查，发现Data.Count属性随着循环删除，每次比较 i < this.dataView2.Count，Count属性也是动态变化的。解决办法:
            string deleteID = this.costomerDataGrid[this.costomerDataGrid.CurrentRowIndex, 6].ToString();
            this.costomer_RecordTableAdapter.Fill(this.realEstatePDADataSet.Costomer_Record);
            MessageBox.Show("过滤前的dataView集合数："+this.dataView2.Count.ToString());
            this.dataView2.RowFilter = "客户编号 = '" +deleteID+ "'";
            //this.dataView1.Sort = "来访时间";
            MessageBox.Show("过滤条件：" + deleteID);
            MessageBox.Show("过滤后的dataView集合数："+this.dataView2.Count.ToString());
            this.costomer_RecordBindingSource.EndEdit();
            while(this.dataView2.Count!=0)
            {
                MessageBox.Show("删除第" + Convert.ToSingle(this.dataView2.Count)+ "条记录");
                this.costomer_RecordBindingSource.RemoveAt(this.dataView2.Count-1);
            }
            this.costomer_RecordTableAdapter.Update(this.realEstatePDADataSet.Costomer_Record);
                MessageBox.Show("删除成功!");
