如何使用Eval将sql varbinary数据(图像)绑定到图像?
像这样:
<image src = <%# Eval("imageBinaryData") %> />
最佳答案
您需要使用HttpHandler来获取数据并将其流回。然后,您将从ASPX页面链接到处理程序。
<img class="mainEventsImage"
src='<%# Eval("MainImagePath").ToString().Replace("\\", "/") %>'
alt='<%# Eval("Title") %>' runat="server" />
if (reader.Read())
{
int bufferSize = 100;
byte[] bytes = new byte[bufferSize];
long bytesRead;
long readFrom = 0;
do
{
bytesRead = reader.GetBytes(0, readFrom, bytes, 0, bufferSize);
context.Response.ContentType = "image/jpeg";
context.Response.BinaryWrite(bytes);
readFrom += bufferSize;
}
while (bytesRead == bufferSize);
}
reader.Close();
