使用visual studion2010做单元测试，数据源为csv，运行结果报错

Question

一个简单的乘法例子
///
///Multiply 的测试
///
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "|DataDirectory|\MultiplyTest.csv", "MultiplyTest#csv", DataAccessMethod.Sequential), DeploymentItem("UTProject\MultiplyTest.csv"), TestMethod()]
public void MultiplyTest1()
{
int a = (int)TestContext.DataRow["a"]; // TODO: 初始化为适当的值
int b = (int)TestContext.DataRow["b"]; // TODO: 初始化为适当的值
int expected = (int)TestContext.DataRow["c"]; // TODO: 初始化为适当的值
int actual;
actual = MathUtility.Multiply(a, b);
Assert.AreEqual(expected, actual);
//Assert.Inconclusive("验证此测试方法的正确性。");
}
数据源是csv，运行结果报错：
未通过 00:00:00.0672983 0 测试方法 UTProject.MathUtilityTest.MultiplyTest1 引发了异常:
System.ArgumentException: 列“a”不属于表 。
csv文档中数据

Answer 1

aSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "|DataDirectory|\MultiplyTest.csv", "MultiplyTest#csv", DataAccessMethod.Sequential), DeploymentItem("UTProject\MultiplyTest.csv"), TestMethod()]

int actual;
actual = MathUtility.Multiply(a, b);
Assert.AreEqual(expected, actual);
