如何获取数据表中一行的最后一个单元格？

Question

    foreach(DataRow row in dt.Rows)
    {
       foreach(var cell in row.ItemArray)
       {
          builder.Append(cell.ToString());
          if(cell != row.lastcell)
             builder.Append("\t");
       }
       builder.Append(Environment.NewLine);
    }

i need to make sure that cell!=the last cell in the row

how do i do this?

Answer 1

You don't need to do that. Just use string.Join instead:

string[] strings = Array.ConvertAll(row.ItemArray, x => x.ToString());
builder.Append(string.Join("\t", strings);

Answer 2

这将为您提供最后一行：

row = (DataRow)table.Rows[table.Rows.Count-1];

Answer 3

You could completely avoid the last cell if you use a for loop:

for (int i=0; i<row.ItemArray-2;i++)
{
    // do your code here, we are taking off the last cell with the -2
}

Answer 4

使用row.ItemArray [row.ItemArray.Length-1]获取最后一个单元格的值

Answer 5

foreach(DataRow row in dt.Rows)
{
   string separator = String.Empty;
   foreach(var cell in row.ItemArray)
   {
      builder.Append(separator);
      builder.Append(cell.ToString());
      separator  = "\t";
   }
   builder.Append(Environment.NewLine);
}
