Question

我的项目中有这段特定的代码：

if (type == 1)
{
    if (line.StartsWith(user.PadRight(FieldLengths1[0])))
        keep = true;
}
else if (type == 2)
{
    if (line.StartsWith(user.PadRight(FieldLengths2[0])))
        keep = true;
}

最初，缩进是不同的。 else-if应该链接到＆＃34; if（type == 1）＆＃34;，正如内容所暗示的那样。但Visual Studio似乎已经改变了我的缩进，建议将它链接到下一个if（if（line.startswith ...））

这可能相当于

if (type == 1)
{
    if (line.StartsWith(user.PadRight(FieldLengths1[0])))
        keep = true;
    else if (type == 2)
    {
        if (line.StartsWith(user.PadRight(FieldLengths2[0])))
            keep = true;
    }
}

或者对此：

 excelExport: function (e) {
                    if (exportFlag) {

                        e.sender.showColumn("INS_TYPE");
                        e.sender.showColumn("ErollementYear");

                        e.preventDefault();
                        exportFlag = true;
                        setTimeout(function () {
                            e.sender.saveAsExcel();
                        });
                    } else {
                        e.sender.hideColumn(0);
                        exportFlag = false;
                    }
                }

Here is complete code for binding

var gridReadUrl = baseUrl + 'Insurance/GetInsuranceDisputes';

var exportFlag = true;
$(document).ready(function () {

    InsuranceGrid.Initialize('#ActiveGrid');

});

    var initialize = function () {

        var grid = $("#ActiveGrid"); //$('div', container);

                    endswith: "Ends With"

function onChange(e) {

我想知道else-if如何表现没有括号，以及究竟是什么决定它会链接到哪个？

Answer 1

else关键字始终与最近的if。

C＃如果是else的优先级if if
