每次运行应用程序时都会收到此异常。我知道它是什么
XamlParseException未处理。
'在类型'chrm.MainWindow'上调用与指定匹配的构造函数 绑定约束引发了异常。行号“3”和行位置“9”。
我的代码
GoogleChrome.cs
namespace chrm
{
class GoogleChrome
{
public List<URL> URLs = new List<URL>();
public IEnumerable<URL> GetHistory()
{
// Get Current Users App Data
string documentsFolder = Environment.GetFolderPath
(Environment.SpecialFolder.ApplicationData);
string[] tempstr = documentsFolder.Split('\\');
string tempstr1 = "";
documentsFolder += "\\Google\\Chrome\\User Data\\Default";
if (tempstr[tempstr.Length - 1] != "Local")
{
for (int i = 0; i < tempstr.Length - 1; i++)
{
tempstr1 += tempstr[i] + "\\";
}
documentsFolder = tempstr1 + "Local\\Google\\Chrome\\User Data\\Default";
}
// Check if directory exists
if (Directory.Exists(documentsFolder))
{
return ExtractUserHistory(documentsFolder);
}
return null;
}
IEnumerable<URL> ExtractUserHistory(string folder)
{
// Get User history info
DataTable historyDT = ExtractFromTable("urls", folder);
// Get visit Time/Data info
DataTable visitsDT = ExtractFromTable("visits",
folder);
// Loop each history entry
foreach (DataRow row in historyDT.Rows)
{
// Obtain URL and Title strings
string url = row["url"].ToString();
string title = row["title"].ToString();
// Create new Entry
URL u = new URL(url.Replace('\'', ' '),
title.Replace('\'', ' '),
"Google Chrome");
// Add entry to list
URLs.Add(u);
}
// Clear URL History
DeleteFromTable("urls", folder);
DeleteFromTable("visits", folder);
return URLs;
}
void DeleteFromTable(string table, string folder)
{
SQLiteConnection sql_con;
SQLiteCommand sql_cmd;
// FireFox database file
string dbPath = folder + "\\History";
// If file exists
if (File.Exists(dbPath))
{
// Data connection
sql_con = new SQLiteConnection("Data Source=" + dbPath +
";Version=3;New=False;Compress=True;");
// Open the Conn
sql_con.Open();
// Delete Query
string CommandText = "delete from " + table;
// Create command
sql_cmd = new SQLiteCommand(CommandText, sql_con);
sql_cmd.ExecuteNonQuery();
// Clean up
sql_con.Close();
}
}
DataTable ExtractFromTable(string table, string folder)
{
SQLiteConnection sql_con;
SQLiteCommand sql_cmd;
SQLiteDataAdapter DB;
DataTable DT = new DataTable();
// FireFox database file
string dbPath = folder + "\\History";
// If file exists
if (File.Exists(dbPath))
{
// Data connection
sql_con = new SQLiteConnection("Data Source=" + dbPath +
";Version=3;New=False;Compress=True;");
// Open the Connection
sql_con.Open();
sql_cmd = sql_con.CreateCommand();
// Select Query
string CommandText = "select * from " + table;
// Populate Data Table
DB = new SQLiteDataAdapter(CommandText, sql_con);
DB.Fill(DT);
// Clean up
sql_con.Close();
}
return DT;
}
}
}
URL.cs
namespace chrm
{
class URL
{
string url;
string title;
string browser;
public URL(string url, string title, string browser)
{
this.url = url;
this.title = title;
this.browser = browser;
}
public string getData()
{
return browser + " - " + title + " - " + url;
}
}
}
最后是Mainwindow.xaml.cs
namespace chrm
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
GoogleChrome ch = new GoogleChrome();
public MainWindow()
{
InitializeComponent();
ch.GetHistory();
}
}
}
当我把调试放在cs文件中时..我看到它不会进入DataTable ExtractFromTable(字符串表,字符串文件夹)。所以我只在mainwindow中收到错误。
现在该怎么办?
好的..当我抓住它给我的例外时
System.IO.FileLoadException:混合模式程序集是针对运行时的版本“v2.0.50727”构建的,如果没有其他配置信息,则无法在4.0运行时加载。\ r \ n在chrm.GoogleChrome.ExtractFromTable(String table) ,字符串文件夹)\ r \ n位于D:\ html5 \ chrm \ chrm \ GoogleChrome.cs中的chrm.GoogleChrome.ExtractUserHistory(String文件夹):第45行\ r \ n位于Chrm.GoogleChrome.GetHistory()中的D:\ html5 \ chrm \ chrm \ GoogleChrome.cs:第35行\ r \ n位于D:\ html5 \ chrm \ chrm \ MainWindow.xaml.cs中的chrm.MainWindow..ctor():第33行
是因为我使用的dll是v2.0 ..我的应用程序需要4.0?
答案 0 :(得分:0)
根据您的IOException
,我确实会说这是一个错误,因为您在尝试使用针对.NET 2.0构建的DLL时在.NET 4.0中进行编译
尝试在app.config文件的配置部分添加此项。您可以尝试在主应用程序或DLL中使用上面的代码,如果需要:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v4.0"/>
</startup>
