如何从datagridview编辑并保存新的更改 [英] How to edit from the datagridview and save new changes

问题描述

我有一个资源文件，我读取数据并将其加载到网格视图。现在我希望用户能够从网格编辑并单击保存按钮，将其保存为resx的新文件？我怎么做？这是读取文件的代码。

 oDataSet =  new 数据集（）; 
  //  现在正在读取所选路径中的文件 
 XmlReadMode omode = oDataSet.ReadXml（PathSelection）; 
 
  for （ int  i =  0 ; i <  oDataSet.Tables [ 2 ]。Rows.Count; i ++ ）
 {
  string  comment = oDataSet.Tables [  data]。行[i] [ 2 ]。ToString（）; 
  string  font = Between（comment，  [字体]，  [/ Font]）; 
  string  datestamp = Between（comment，  [DateStamp]，  [/ DateStamp]）; 
  string  commentVal = Between（comment，  [Comment]，  [/ Comment]）; 
 
  string  [] row =  new   string  [] 
 {
 oDataSet.Tables [  data].Rows[i][ 0 ]。ToString（），
 oDataSet.Tables [   data]。行[i] [ 1 ]。ToString（），
字体，
 datestamp，
 commentVal 
}; 
 
 Gridview_Input.Rows.Add（row）; 

代码，我试过但这不起作用。任何帮助请

  foreach （DataGridViewRow _gd  in  Gridview_Input.Rows）
 {
 DataRow _row = oDataSet.Tables [ 数据] NEWROW（）; 
 _row [ 0 ] = oDataSet.Tables [  data]。行[ 0 ] [ 0 ]。ToString（）; 
  if （_gd.Cells [ 1 ]。Value.ToString（）！=  null ）
 _row [ 1 ] = _gd.Cells [ 1 ] Value.ToString（）; 
 
  if （_gd.Cells [ 2 ]。Value.ToString（） ！=  null ）
 _row [ 2 ] = _gd.Cells [ 2 ] Value.ToString（）; 
 
  if （_gd.Cells [ 3 ]。Value.ToString（） ！=  null ）
 _row [ 3 ] = _gd.Cells [ 3 ] Value.ToString（）; 
 
  if （_gd.Cells [ 4 ]。Value.ToString（） ！=  null ）
 _row [ 4 ] = _gd.Cells [ 4 ] Value.ToString（）; 
 
 oDataSet.Tables [  data]。Rows.Add（_row ）; 
 Gridview_Input.Rows.Add（_row）; 
}

I have a resource file which i read the data and load it to the grid-view. now i want the user to be able to edit from the grid and click save button which will save it as a new file of resx? how do i do that? this is the code for reading the file.

oDataSet = new DataSet();
//now am reading the files from the path that is selected
XmlReadMode omode = oDataSet.ReadXml(PathSelection);

for (int i = 0; i < oDataSet.Tables[2].Rows.Count; i++)
{
    string comment = oDataSet.Tables["data"].Rows[i][2].ToString();
    string font = Between(comment, "[Font]","[/Font]");
    string datestamp = Between(comment, "[DateStamp]", "[/DateStamp]");
    string commentVal = Between(comment, "[Comment]", "[/Comment]");

    string[] row = new string[]
    {
        oDataSet.Tables["data"].Rows[i][0].ToString(),
        oDataSet.Tables["data"].Rows[i][1].ToString(),
        font,
        datestamp,
        commentVal
    };

    Gridview_Input.Rows.Add(row);

code that i tried but this didn't work. any help please

foreach (DataGridViewRow _gd in Gridview_Input.Rows)
               {
                   DataRow _row = oDataSet.Tables["data"].NewRow();
                   _row[0] = oDataSet.Tables["data"].Rows[0][0].ToString();
                   if (_gd.Cells[1].Value.ToString() != null)
                       _row[1] = _gd.Cells[1].Value.ToString();

                   if (_gd.Cells[2].Value.ToString() != null)
                       _row[2] = _gd.Cells[2].Value.ToString();

                   if (_gd.Cells[3].Value.ToString() != null)
                       _row[3] = _gd.Cells[3].Value.ToString();

                   if (_gd.Cells[4].Value.ToString() != null)
                       _row[4] = _gd.Cells[4].Value.ToString();

                   oDataSet.Tables["data"].Rows.Add(_row);
                   Gridview_Input.Rows.Add(_row);
