输入格式不正确 [英] input was not in correct format

问题描述

int sum = 0;

for (int i = 0; i < dataGridView1.Rows.Count; ++i)

{
               
 sum += Convert.ToInt32(dataGridView1.Rows[i].Cells[38].Value);
            
}
            
txt_balance.Text = sum.ToString();
            
txt_total.Text = sum.ToString();
            
txt_Exempt.Text = sum.ToString();

我遇到错误输入字符串不是格式正确。如果datagridview行增加，我想计算列值。我尝试了，当我执行这个错误时

推荐答案

在你的某个地方loop dataGridView1.Rows [i] .Cells [38] .Value 具有无效的整数值（作为字符串）。我建议你调试你的应用程序以找到问题。

somewhere during your loop dataGridView1.Rows[i].Cells[38].Value has invalid integer value (as string). I suggest you debug your application to find the probelm.

sum值包含特殊字符......这就是为什么它显示'是错误

the sum value contains special character... that why it show''s the error
