你那个imagepath倒底是路径,还是包含有完整的文件名的,如果没有文件名那就应该加上前面的imagename,另外,未做测试,但感觉imagepath中的\应该替换为/

sqlComGet.CommandText = "select * from peopleimage where name='" + Session["UserName"].ToString() + "'";
SqlDataReader sqlDr = sqlComGet.ExecuteReader(); //创建SqlDataReader对象
if (sqlDr.Read())
{
Image1.ImageUrl = sqlDr["imagepath"].ToString().Replace("\\","/").Trim('/')+"/"+sqlDr["imagename"].ToString();
}
