net中一些所封装的类

之类的类，太多了

//=========加密=================
public static string Encrypto(string Source) 
{
System.Security.Cryptography.HashAlgorithm HashCryptoService;
HashCryptoService = new System.Security.Cryptography.SHA1Managed();
byte[] bytIn = System.Text.UTF8Encoding.UTF8.GetBytes(Source);
byte[] bytOut = HashCryptoService.ComputeHash(bytIn);
return Convert.ToBase64String(bytOut);
}

//=========3大显示数据绑定=================
public void BindBaseList(System.Web.UI.WebControls.BaseDataList bdl_object,DataSet ds, string tbName)
{
bdl_object.DataSource=ds.Tables[tbName];
bdl_object.DataBind();
}

//=========DropDownList数据绑定=================
public static void CreateDropDownList(DropDownList ddl_object, DataTable dt, string s_text,string s_value)
{
ddl_object.DataSource = dt;
ddl_object.DataTextField = s_text;
ddl_object.DataValueField = s_value;
ddl_object.DataBind();
}

#region================js控制=================
