DataGridViewDataGridView有人知道一种快速快捷的方法吗？最简单的方法是将文本文件导入DataTable，然后通过DataSource属性将DataTable绑定到DataGridView 您的文件看起来是固定宽度或分隔的数据文件。有很多库可以帮助将这些文件读入数据表，例如在codeproject.com上 下面是如何使用上面链接的GenericParser：
// DataFilePath stores the path + file name of your data file.
using (var p = new GenericParsing.GenericParserAdapter(DataFilePath)) {
// Assumes your data file is fixed width, with the column widths given in the array.
p.ColumnWidths = new int[] { 8, 12, 9, 9, 5, 11 };
p.FirstRowHasHeader = true;
DataTable dt = p.GetDataTable();
dataGridView1.DataSource = dt;
}
请注意，您需要在项目中添加GenericParsing.dll作为引用。您可以使用数据源和Microsoft文本文件驱动程序

{
#if X86 // 32-bit
string _connectionStringTemplate = "Driver={{Microsoft Text Driver (*.txt; *.csv)}};Extensions=asc,csv,tab,txt;Persist Security Info=False;Dbq={0}";
#else // 64-bit
string _connectionStringTemplate = "Driver={{Microsoft Access Text Driver (*.txt, *.csv)}};Dbq={0};Extensions=asc,csv,tab,txt";

string connectionString = string.Format(_connectionStringTemplate, @"C:\Temp\");

using (OdbcDataAdapter adapter = new OdbcDataAdapter(selectAll, connection))
{
//Fills dataset with the records from file
adapter.Fill(dataTable);
return dataTable;
}
}
}
}
然后，只需将DataTable绑定到DataGridView即可拆分行并循环所有行/列以生成DataTable：
var fileName = this.OpenFileDialog1.FileName;
var rows = System.IO.File.ReadAllLines(fileName);
Char[] separator = new Char [] {' '};
DataTable tbl = new DataTable(fileName);
if (rows.Length != 0) {
foreach (string headerCol in rows(0).Split(separator)) {
tbl.Columns.Add(new DataColumn(headerCol));
}
if (rows.Length > 1) {
for (rowIndex = 1; rowIndex < rows.Length; rowIndex++) {
var newRow = tbl.NewRow();
var cols = rows(rowIndex).Split(separator);
for (colIndex = 0; colIndex < cols.Length; colIndex++) {
newRow(colIndex) = cols(colIndex);
}
tbl.Rows.Add(newRow);
}
}
}
var fileName=this.OpenFileDialog1.fileName；
var rows=System.IO.File.ReadAllLines（文件名）；
字符[]分隔符=新字符[]{''}；
DataTable tbl=新的DataTable（文件名）；
如果（rows.Length！=0）{
foreach（行中的字符串headerCol（0）.拆分（分隔符））{
tbl.Columns.Add（新数据列（headerCol））；
}
如果（rows.Length>1）{
对于（rowIndex=1；rowIndex然后将此数据表用作DataGridView的数据源。您能再解释一下发生了什么吗？我从未使用过DataTable或DataGridView..：（您好@theNoobGuy，我想如果您是DataTable和GridView对象的新手，我建议您快速使用Google和Samilia，尤其是DataTable对象，因为它对于在.Net中处理数据至关重要。如果对上述代码有任何特定问题，请告诉我。在newRow获取“预期的方法、委托或事件”错误（colIndex）=cols（colIndex）；我想我会向未来的用户澄清，for循环中的错误可以通过使用int声明colIndex和rowIndex以及整数来修复，当在for循环中指向它们时，使用方括号[]而不是方括号（），与行（0）一样，应该是行[0]。谢谢Tim。
