Bitmap(myStream)的参数无效 是什么错误？？？各位帮帮忙
byte[] buffByte = null;
DataTableReader userReader = userTable.CreateDataReader();
while (userReader.Read())
{
if (userReader["个人头像"] == null)
{ }
else
buffByte = (byte[])userReader["个人头像"];
}
MemoryStream myStream = new MemoryStream(buffByte);
Bitmap bmpt = new Bitmap(myStream);
myStream.Close()
当我运行的时候就提示：new Bitmap(myStream)的参数无效
DataTableReader userReader = userTable.CreateDataReader();
while (userReader.Read())
{
if (userReader["个人头像"] == null)
{ }
else
buffByte = (byte[])userReader["个人头像"];
}
MemoryStream myStream = new MemoryStream(buffByte);
Bitmap bmpt = new Bitmap(myStream);
myStream.Close()

如果数据库存的是Image的字段类型，
byte[] buffByte = null;
DataTableReader userReader = userTable.CreateDataReader();
if(userReader.Read())
{
if (userReader["个人头像"] == DBNull.Value)
{
//停止
}
else
buffByte = (byte[])userReader["个人头像"];
}
MemoryStream myStream = new MemoryStream(buffByte);
Bitmap bmpt = new Bitmap(myStream);
myStream.Close()
byte[] buffByte = null;
DataTableReader userReader = userTable.CreateDataReader();
if(userReader.Read())
{
if (userReader["个人头像"] == DBNull.Value)
{
//停止
}
else
buffByte = (byte[])userReader["个人头像"];
}
MemoryStream myStream = new MemoryStream(buffByte);
Bitmap bmpt = new Bitmap(myStream);
myStream.Close()
