为什么我的DataTable总是返回"true/false"但从不返回字符串？

Question

我正在尝试使用由MySqlDataAdapter填充的DataTable,其中包含博客条目的注释列表.由于某些原因,如果字段"anonymous"设置为"1",则username字段为空,应替换为指定的字符串.

我遇到的问题是,每当我尝试获取字段的值时,我会得到"true"或"false".我的代码看起来像这样:

DataTable modifiedComments = new DataTable();
// The function GetCommentsById() returns a MySqlDataAdapter with the result of the query
MySqlDataAdapter commentsContainer = Wb.Entry.GetCommentsById(imageId);
commentsContainer.Fill(modifiedComments);
commentsContainer.Dispose();

    foreach (DataRow row in modifiedComments.Rows)
        {
            string status;
            // This never returns true, so we always get into the else
            if (row["anonymous"] == "1")
            {
                    status = "You are anonymous";
            }
            else
            {
                    status = "You are not anonymous";
            }
        }

        viewImageCommentsRepeater.DataSource = modifiedComments;
        viewImageCommentsRepeater.DataBind();

Answer 1

该字段可能是一个"位"字段类型,它在ADO.NET中映射到布尔值

只需检查是真是假:

if ((bool)row["anonymous"])
