C＃将int方法转换为字符串方法

Question

我正在使用Fusionchart，我需要标记轴。 它使用int但我需要一个轴的字符串

 public int GetyAxisName(int chartId)
{
    Chart_AttributeModel chart_AttributeModel = new Chart_AttributeModel();
    List<Chart_Attribute> attributes = chart_AttributeModel.GetChart_AttributeByChart(chartId);

    AttributeModel attributeModel = new AttributeModel();

    int yAxisName = new int();
    foreach (Chart_Attribute ca in attributes)
    {
        Attribute a = attributeModel.GetAttribute(ca.AID);
        if (a.Name == "yAxisName")
        {
            yAxisName = Convert.ToInt32(ca.Value);
        }
    }

    return yAxisName;
}

但是，如果我想将其更改为字符串，它就不起作用。 代码有什么问题？

 public string GetyAxisName(int chartId)
{
    Chart_AttributeModel chart_AttributeModel = new Chart_AttributeModel();
    List<Chart_Attribute> attributes = chart_AttributeModel.GetChart_AttributeByChart(chartId);

    AttributeModel attributeModel = new AttributeModel();

    string yAxisName = new string();
    foreach (Chart_Attribute ca in attributes)
    {
        Attribute a = attributeModel.GetAttribute(ca.AID);
        if (a.Name == "yAxisName")
        {
            yAxisName = Convert.ToString(ca.Value);
        }
    }

    return yAxisName;
}

唯一可见的错误是string yAxisName1 = new string();

String不包含带0参数的构造函数。所以把它string yAxisName1 = "";
