datagridview中的加密数据 [英] Encrypted data in datagridview

问题描述

大家好..我对datagridview很新，我想知道有没有办法在访问中转换加密数据并在datagridview中显示它？我正在使用C＃和微软访问


通常这是如何在datagridview中显示数据：


OleDbConnection conn = new OleDbConnection（" Provider = Microsoft.Jet.OLEDB.4.0; Data Source =""）;

OleDbCommand command = conn.CreateCommand（）;

string strSQL =" SELECT * FROM雇员英寸;

ds = new DataSet（）;

conn.Open（）;


command.CommandText = strSQL;

OleDbDataAdapter adapter = new OleDbDataAdapter（command）;

adapter.Fill（ds）;

dataGridView1.DataSource = ds.Tables [0];

dataGridView1.ReadOnly = true;

conn.Close（）;

我应该在数据网格中显示之前更改为解密这些数据？ div class =h2_lin>解决方案

你知道如何取消加密吗？如果是这样，只需对数据集中的数据kep运行解密？

是..我知道如何解密它。但我正在做的是一次解密1

例如。 temp =（string）read [" Username"];

encryption.decrypt（temp，true）;

这只解密用户名..问题是我不知道如何在datagrid中显示它。所有这一切，我只在一个while循环使用这个方法。

例如。

while（read.read（））

{

//解密

}

好吧，填充你的DataSet，然后遍历数据集。

hi guys..im new to datagridview and im wondering is there a way to convert an encrypted data in access and show it in a datagridview? im using C# and microsoft access

normally this is how to show data in datagridview:

OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source="");
OleDbCommand command = conn.CreateCommand();
string strSQL = "SELECT * FROM Employee";
ds = new DataSet();
conn.Open();

command.CommandText = strSQL;
OleDbDataAdapter adapter = new OleDbDataAdapter(command);
adapter.Fill(ds);
dataGridView1.DataSource = ds.Tables[0];
dataGridView1.ReadOnly = true;
conn.Close();
where should i change to decrypt those data before showing it in the datagrid?

解决方案

Do you know how to un-encrypt it? If so, just run the decrypting on the data kep in the dataset?

yes..i know how to decrypt it. but what im doing is to decrypt it 1 at a time
eg. temp=(string)read["Username"];
encryption.decrypt(temp, true);
this decrypts the username only..the problem is i dont know how to show this in the datagrid. all this while i used this method only in a while loop.
eg.
while(read.read())
{
//decrypt
}

Well, populate your DataSet, then loop through the dataset.
