我是单位测试我的一个功能.这是我的代码：
public void TestLabels()
{
//Step 1: Creating a mock table with columns exactly like in the real table.
DataTable table = new DataTable();
DaTarow mydaTarow;
mydaTarow = table.NewRow();
//Step 2: Adding the row as same as the Real Data!
mydaTarow["Name"] = "Test";
mydaTarow["Address"] = "00000 ST.";
mydaTarow["ZipCode"] = "77665";
mydaTarow["Tracking#"] = "";
table.Rows.Add(mydaTarow);
foreach (DataColumn column in table.Columns)
Console.WriteLine(column.ColumnName);
//Step 3: Call method we are testing.
var updateTable = IceTechUPSClient.Instance.CreateLabels(table);
foreach (DaTarow row in updateTable.Rows)
{
var trackingNumber = row["Tracking#"].ToString();
Assert.IsFalse(String.IsNullOrWhiteSpace(trackingNumber),"Expecting tracking number generated for every row!");
Assert.IsTrue(File.Exists(trackingNumber + ".gif"));
}
}
现在我收到一个错误：列“名称”不属于表.正如你所看到的,我在这里指定了列名“Name”,并添加了该行.那么为什么我得到这个错误？任何帮助？
谢谢！
解决方法
您尚未设置列(除非您错过了示例中的某些代码).
您需要创建具有所需名称的列,然后才能访问它们：
var columnSpec = new DataColumn
{
DataType = typeof(string),ColumnName = "Name"
};
this.table.Columns.Add(columnSpec);
当您将AutoGenerateColumns设置为true(默认值)时,如果您从数据库中读取数据,则无需明确地将其视为幕后完成.
