asp.net導出Excel亂碼的原因和解決方案

本篇內容介紹了“asp.net導出Excel亂碼的原因和解決方案”的有關知識，在實際案例的操作過程中，不少人都會遇到這樣的困境，接下來就讓小編帶領大家學習一下如何處理這些情況吧！希望大家仔細閱讀，能夠學有所成！

復制代碼 代碼如下:

protected void Excel_Click(object sender, EventArgs e)
{
Response.Charset = "UTF-8";
Response.ClearContent();
Response.Clear();
Response.ContentEncoding = System.Text.Encoding.UTF8;
Response.HeaderEncoding = System.Text.Encoding.UTF8;
Response.AddHeader("content-disposition", "attachment; filename=MyExpress.xls");
Response.ContentType = "application/excel";
System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
// turn off paging
GridView1.AllowPaging = false;
dataBind();
GridView1.RenderControl(htw);
Response.Write(sw.ToString());
Response.End();
// turn the paging on again
GridView1.AllowPaging = true;
dataBind();
}

關鍵:

復制代碼 代碼如下:

Response.Charset = "UTF-8";//添加編碼格式
Response.ClearContent();
Response.Clear();
Response.ContentEncoding = System.Text.Encoding.UTF8;//表格內容添加編碼格式
Response.HeaderEncoding = System.Text.Encoding.UTF8;//表頭添加編碼格式

上邊如果解決不了還可以用

復制代碼 代碼如下:

Response.ClearContent();
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=sumlate.xls");
Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");
Response.ContentType = "application/excel";
System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
if (GridView2.Rows.Count > 0)
{
GridView2.RenderControl(htw);
}
else
{
GridView1.RenderControl(htw);
}
Response.Write(sw.ToString());
Response.End();

關鍵：

復制代碼 代碼如下:

Response.Charset = "GB2312";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("GB2312");

注意觀察，主要原因其實就是編碼格式問題。

現在就能防止導出時候亂碼問題了
