Question

我需要尝试部分搜索用户，现在，我的代码只是根据EXACT用户名查找结果。我怎么能这样做？

我的代码可以在下面找到，请注意我正在使用“@ 0”，这似乎阻止我使用％@ 0％。

Here's my code:
@{
    Layout = "~/Admin/_SiteLayout.cshtml";

    var db = Database.Open("MikZeRCoding2");
    var userSearchQuery = "SELECT * FROM [Users] WHERE UserName = @0";

    var UsernameSearch = "";
    var ErrorMessage = "";
    var searchString = Request.Form["search-username"];

    if (IsPost) {
        UsernameSearch = Request.Form["search-username"];

        if (UsernameSearch.IsEmpty()) {
            ErrorMessage = "You didn't search for anything.";
        }

        if (!UsernameSearch.IsEmpty() && db.QueryValue(userSearchQuery, UsernameSearch) == null) {
            ErrorMessage = "No results for '" + searchString + "' were found...";
        }

        if (searchString == "bitch") {
            ErrorMessage = "Bitch spotted in-front of your pc monitor.";
        }

        else {

        }
    }
}

<form method="post" action="">
    <div class="input-group">
        <input type="text" name="search-username" placeholder="Search for a user" class="form-control" />
        <span class="input-group-btn">
            <button class="btn btn-default glyphicon glyphicon-search" type="button"></button>
        </span>
    </div>
    <input type="submit" value="Search" />

    @foreach(var user in db.Query(userSearchQuery, UsernameSearch)) {
        <a href="@Href("~/Admin/Accounts/User", user.UserId)"><span>[ @user.UserId ]</span>  @user.UserName</a>
    }
    @if(!ErrorMessage.IsEmpty()) {
        <div class="alert alert-danger">@ErrorMessage</div>
    }
</form>

我认为你应该可以做到：

var userSearchQuery = "SELECT * FROM [Users] WHERE UserName LIKE '%' + @0 + '%'";

编辑：

@0为空时不返回任何内容：

var userSearchQuery = "SELECT * FROM [Users] WHERE UserName LIKE '%' + @0 + '%' and @0 <> ''";
