bool blnFlag = true;
DataTable mydt = new DataTable("myTableName");
DataColumn mydc;
DataRow mydr;
string strpath = "";
//cvs文件路径string strline;
string [] aryline;
System.IO.StreamReader mysr = new System.IO.StreamReader(strpath);
while((strline = mysr.ReadLine()) != null) { aryline = strline.Split(new char[]{','});
if (blnFlag) { blnFlag = false;
intColCount = aryline.Length;
for (int i = 0;
i < aryline.Length;
i++) { mydc = new DataColumn(aryline[i]);
mydt.Columns.Add(mydc);
} } mydr = mydt.NewRow();
for (int i = 0;
i < intColCount;
i++) { mydr[i] = aryline[i];
} mydt.Rows.Add(mydr);
}mydt.Rows.RemoveAt(0);
dataGridView1.DataSource = mydt.DefaultView;
dataGridView1.Columns[0].HeaderText = "编号";
方法二、当做一个数据源读取，常用的sql语句都能执行的 using (OleDbConnection conn = new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=C:\csv\;
Extended Properties='Text;
'")){DataTable dtTable = new DataTable();
OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM [Test.csv]", conn);
try {adapter.Fill(dtTable);
}catch (Exception ex){dtTable = new DataTable();
}this.GridView1.DataSource = dtTable;
this.GridView1.DataBind();
} 今天要写一个C++读取CSV文件的，后来在百度上搜索，找到了，但是代码运行就出错，代码有问题，后来Google了下，找到老外的一个代码，就使了一下，绝对好用，代码简单，太感谢了。我感觉还是要把英文学好呀
