Question

我在C＃中使用Awesomium，我正在将变量拖出javascript。

运行的代码：

           if (GotCategories == false) {
            if (WebBrowser.ExecuteJavascriptWithResult("finished").ToString() == "true" && WebBrowser.IsDocumentReady == true) {
                int Level1Len = Convert.ToInt32(WebBrowser.ExecuteJavascriptWithResult("all_categories.length").ToString());
                for (int i = 0; i < Level1Len - 1; i++) {
                    string Level1 = WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].title");
                    string Level1ID = WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].id");
                    TreeNode treenode = new TreeNode(Level1);
                    CatsTree.Nodes.Add(treenode);
                    int Level2Len = Convert.ToInt32(WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub.length").ToString());
                    for (int j = 0; j < Level2Len; j++) {
                        string Level2 = WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub[" + j + "].title");
                        string Level2ID = WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub[" + j + "].id");
                        treenode = new TreeNode(Level2);
                        CatsTree.Nodes[i].Nodes.Add(treenode);
                        int Level3Len = Convert.ToInt32(WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub[" + j + "].sub.length").ToString());
                        for (int k = 0; k < Level3Len; k++) {
                            string Level3 = WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub[" + j + "].sub[" + k + "].title");
                            string Level3ID = WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub[" + j + "].sub[" + k + "].id");
                            treenode = new TreeNode(Level3);
                            CatsTree.Nodes[i].Nodes[j].Nodes.Add(treenode);
                            if (WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub[" + j + "].sub[" + k + "].sub.length").IsInteger == true) {
                                string Level4Len = Convert.ToInt32(WebBrowser.ExecuteJavascriptWithResult("all_categories[" + i + "].sub[" + j + "].sub[" + k + "].sub.length").ToString());

虽然发生了一个奇怪的问题..

如果我运行它现在是怎么回事Level4Len抛出异常错误

输入字符串的格式不正确。

虽然..奇怪的是，如果我放一个MessageBox.Show(Level4Len);我没有收到错误和...以及所显示的输出完全正常，因为它们应该是。

我见过的最奇怪的事情......

在c＃中使用awesomium和javascript最奇怪的问题
