c# - 用c#填充javascript数组

Question

如何在后面的代码中用 C# 填充在 javascript 中定义的数组？

编辑:

这是我的代码

protected void Page_Load(object sender, System.EventArgs e)
{
string[] locations = new string[] {
    "Las Vegas",
    "Los Angeles",
    "Tampa",
    "New York",
    "s",
    "sss"
};
string jsArray = GetJSArrayForVBArray(locations);
this.ClientScript.RegisterArrayDeclaration("usernames", jsArray);
}

private string GetJSArrayForVBArray(string[] vbArray)
{
StringBuilder myResult = new StringBuilder();
foreach (string item in Constants.vbArray) {
    {
        myResult.Append(",'" + item + "'");
    }
}
if ((myResult.Length > 0)) {
    return myResult.ToString().Substring(1);
} else {
    return "";
}
}

Javascript:

<script type="text/javascript">
    $(function () {
        var usernames = new Array();
        $("#tags").autocomplete({
            source: usernames
        });
    });
</script>

使用JavaScriptSerializer类(class)。像下面这样的事情应该做

protected void Page_Load(object sender, System.EventArgs e)
{
    string[] locations = new string[] {
        "Las Vegas",
        "Los Angeles",
        "Tampa",
        "New York",
        "s",
        "sss"
    };

    JavaScriptSerializer serializer = new JavaScriptSerializer();

    string jsArray = serializer.Serialize(locations);
    this.ClientScript.RegisterClientScriptBlock(this.GetType(), "locations", jsArray, true);
}
