C# VS 2010单元测试和无符号类型
我正在将我的单元测试从NUnit转换为VisualStudio 2010单元测试框架。以下C# VS 2010单元测试和无符号类型,c#,unit-testing,nunit,migration,mstest,C#,Unit Testing,Nunit,Migration,Mstest,我正在将我的单元测试从NUnit转换为VisualStudio 2010单元测试框架。以下bytetoushortest()方法失败并显示消息: Assert.AreEqual失败。预期:。实际值:。 [TestMethod, CLSCompliant(false)] public void ByteToUShortTest() { var array = new byte[2]; Assert.AreEqual(ByteToUShort(array), new ushort[1
bytetoushortest()
方法失败并显示消息:
Assert.AreEqual失败。预期:。实际值:。
[TestMethod, CLSCompliant(false)]
public void ByteToUShortTest()
{
var array = new byte[2];
Assert.AreEqual(ByteToUShort(array), new ushort[1]);
}
测试调用的代码是:
[CLSCompliant(false)]
public static ushort[] ByteToUShort(byte[] array)
{
return ByteToUShort(array, 0, array.Length, EndianType.LittleEndian);
}
public enum EndianType
{
LittleEndian,
BigEndian
}
[CLSCompliant(false)]
public static ushort[] ByteToUShort(byte[] array, int offset, int length, EndianType endianType)
{
// argument validation
if ((length + offset) > array.Length)
throw new ArgumentException("The length and offset provided extend past the end of the array.");
if ((length % 2) != 0)
throw new ArgumentException("The number of bytes to convert must be a multiple of 2.", "length");
var temp = new ushort[length / 2];
for (int i = 0, j = offset; i < temp.Length; i++)
{
if (endianType == EndianType.LittleEndian)
{
temp[i] = (ushort)(((uint)array[j++] & 0xFF) | (((uint)array[j++] & 0xFF) << 8));
}
else
{
temp[i] = (ushort)(((uint)array[j++] & 0xFF) << 8 | ((uint)array[j++] & 0xFF));
}
}
return temp;
}
不同的不是类型,而是实例。您正在比较两个不同的数组。不同的不是类型,而是实例。您正在比较两个不同的阵列
