我有sql数据库,我将图像保存为图像位置
例如
D:\Local Pictures\Users\XXXX_XXXX_1.jpg
我正在尝试使用此代码将其放在图片框中
DataConnection myCon = new DataConnection(); // Contains Data Connection String
SqlConnection con1 = new SqlConnection(@"Data Source=.\SQLS2012;Initial Catalog=test;Integrated Security=True");
con1.Open();
SqlDataReader myReader = null;
SqlCommand myCommand = new SqlCommand("SELECT * From USER_TABLE WHERE USERID =" + userIdTextBox.Text,con1);
myReader = myCommand.ExecuteReader();
while (myReader.Read())
{
nameTextBox.Text = (myReader["FIRST_NAME"].ToString());
lnameTextBox.Text = (myReader["LAST_NAME"].ToString());
posTextBox.Text = (myReader["POSITION"].ToString());
emailTextBox.Text = (myReader["E_MAIL"].ToString());
phoneTextBox.Text = (myReader["PHONE"].ToString());
usernameTextBox.Text = (myReader["USERNAME"].ToString());
userLevelTextBox.Text = (myReader["USER_LEVEL"].ToString());
string filename = (myReader["PROFILE_PICTURE"].ToString());
profilePicBox.ImageLocation = filename;
}
当我执行此代码时,我在图像中获得小x图像白色背景。如何修复和加载图像

<强>装载强>
MSDN对此问题并不完全清楚 - ImageLocation property,但似乎设置ImageLocation
属性可能无法正确加载图片,因此您可能会尝试使用{{3}而不是方法:
...
string filename = (myReader["PROFILE_PICTURE"].ToString());
profilePicBox.Load(filename);

ImageLocation
应该可以正常工作,只需确保路径正确并且不使用相对路径 - PictureBox.Load
定位和尺寸:
并确保与尺寸和位置相关的How do I put an image into my picturebox using ImageLocation?可以处理不同的图像尺寸。

在while循环中进行此更改
while (myReader.Read())
{
nameTextBox.Text = (myReader["FIRST_NAME"].ToString());
lnameTextBox.Text = (myReader["LAST_NAME"].ToString());
posTextBox.Text = (myReader["POSITION"].ToString());
emailTextBox.Text = (myReader["E_MAIL"].ToString());
phoneTextBox.Text = (myReader["PHONE"].ToString());
usernameTextBox.Text = (myReader["USERNAME"].ToString());
userLevelTextBox.Text = (myReader["USER_LEVEL"].ToString());
string filename = (myReader["PROFILE_PICTURE"].ToString());
profilePicBox.Image = Image.FromFile(filename )
}
