如何在DataColumn中将两个00添加到“人员主机密钥”之后才会映射到数据库表？
我曾尝试对数据进行隐蔽，但它就像我无法在数据表中格式化它。还尝试为每个循环添加额外的00到字段，但无法使其工作。

答案 0 :(得分：1)
首先 - 最好将Host Key of Staff的{{1}}列的类型从dtExcelData更改为int，否则您将无法将“前置”零添加到它持有的数据。
第二 - 在你的循环中，你只从DataRow获取数据，但实际上并没有改变它。这个循环应该像
string答案 1 :(得分：1)
我会创建一个如下所示的扩展方法
document.getElementById("showHide").onclick = function () {
if ($("#showHide").text() == " show") {
document.getElementById("showHide").innerHTML = "<span class=\"glyphicon glyphicon-eye-close\"></span> hide";
document.getElementById("showHide").blur();
} else {
document.getElementById("showHide").innerHTML = "<span class=\"glyphicon glyphicon-eye-open\"></span> show";
document.getElementById("showHide").blur();
}
}
然后（我已将它用于数据时间并粘贴我的代码）
public static void Modify<T>(this DataColumn dataColumn, Func<object, T> toModify)
{
foreach(DataRow dataRow in dataColumn.Table.Rows)
{
dataRow[dataColumn] = toModify(dataRow[dataColumn]);
}
}
