大家好:最近根据需求 要我们做一个ASP.NET的导出EXCEL ,我在网上借鉴了一段代码,但是用在我这里 ,导出后打开EXCEL发现很多都是乱码 我勒个去!求各位大神们 帮忙看看 这代码哪里有问题:
以下是导出功能的代码:
public static void ExportToSpreadsheet(DataTable table, string name)
{
Random r = new Random();
string rf = "";
for (int j = 0; j < 10; j++)
{
rf = r.Next(int.MaxValue).ToString();
}
HttpContext context = HttpContext.Current;
context.Response.Clear();
context.Response.ContentType = "text/csv";
context.Response.ContentEncoding = System.Text.Encoding.UTF8 ;
context.Response.AppendHeader("Content-Disposition", "attachment; filename=" + name + rf + ".xls");
context.Response.BinaryWrite(System.Text.Encoding.UTF8.GetPreamble());
foreach (DataColumn column in table.Columns)
{
context.Response.Write(column.ColumnName + ",");
//context.Response.Write(column.ColumnName + "(" + column.DataType + "),");
}
context.Response.Write(Environment.NewLine);
double test;
foreach (DataRow row in table.Rows)
{
for (int i = 0; i < table.Columns.Count; i++)
{
switch (table.Columns[i].DataType.ToString())
{
case "System.String":
if (double.TryParse(row[i].ToString(), out test)) context.Response.Write("=");
context.Response.Write("\"" + row[i].ToString().Replace("\"", "\"\"") + "\",");
break;
case "System.DateTime":
if (row[i].ToString() != "")
context.Response.Write("\"" + ((DateTime)row[i]).ToString("yyyy-MM-dd hh:mm:ss") + "\",");
else
context.Response.Write("\"" + row[i].ToString().Replace("\"", "\"\"") + "\",");
break;
default:
context.Response.Write("\"" + row[i].ToString().Replace("\"", "\"\"") + "\",");
break;
}
}
context.Response.Write(Environment.NewLine);
}
context.Response.End();
}
导出后的Excel文件如图: (乱码)
