如何在dtagridview中查找2列的乘法并在第3列中显示答案 [英] how to Find the multiplication of 2 Columns in a dtagridview and display the answer in 3rd column

问题描述

col1 col2 = col3
2 3 = 6

这是我的代码

双倍数量= Double.Parse(row.Cells ["clmQuantity"].Value.ToString());
Double purrate = Double.Parse(row.Cells ["clmPurRate"].Value.ToString());
双倍金额= Math.Round(数量*精制，2);
数量= Double.Parse(row.Cells ["clmAmount"].Value.ToString());

col1 col2 = col3
2 3 = 6

this is my code

Double quantity = Double.Parse(row.Cells["clmQuantity"].Value.ToString());
Double purrate = Double.Parse(row.Cells["clmPurRate"].Value.ToString());
Double amount = Math.Round(quantity * purrate, 2);
amount = Double.Parse(row.Cells["clmAmount"].Value.ToString());

推荐答案

尝试一下，

try this,

foreach (DataGridViewRow row in dataGridView1.Rows)
           {
               row.Cells["clmAmount"].Value = (Double.Parse(row.Cells["clmQuantity"].Value.ToString()) * Double.Parse(row.Cells["clmPurRate"].Value.ToString())).ToString();
           }
