C＃如何从datagridview获取选定的列ID值 [英] C# how to get the selected column ID value from datagridview

问题描述

我有一个DataGridView，用户可以选择列。我希望该选定的列传递ID属性的值。我尝试了很多不同的方法，但是总是回到错误。常规错误消息 - 索引超出范围。必须是非负数，小于收藏的大小...

我尝试过的几行

  int id = Convert.ToInt32（dataGridView1.SelectedRows [0] .Cells [0] .Value）; 
 int id = Convert.ToInt32（dataGridView1.SelectedCells [0]）; 
 int id = Convert.ToInt32（dataGridView1.Rows [0] .Selected）; 
  

解决方案

  Int id = Convert.ToInt32（dataGridView1.Rows [dataGridView1.CurrentRow.Index] .Cells [0] .Value）; 
  

datagridview1.CurrentRow.Index获取所选行的索引。

I have a DataGridView and users can select columns. I want that selected column to pass the value of the ID attribute. I tried quite a few different ways, but always came back with error. Usual error message - "Index was out of range". Must be non-negative and less than the size of the collection...

few of the lines I tried

int id = Convert.ToInt32(dataGridView1.SelectedRows[0].Cells[0].Value);
int id = Convert.ToInt32(dataGridView1.SelectedCells[0]);
int id = Convert.ToInt32(dataGridView1.Rows[0].Selected);

解决方案

Int id= Convert.ToInt32(dataGridView1.Rows[dataGridView1.CurrentRow.Index].Cells[0].Value);

"datagridview1.CurrentRow.Index" gets the index of selected row.
