rules:
|
|
<ul>
|
|
<li>1: only converts if the value is in the range of the target type.</li>
|
|
<li>2: only converts if the value, not the position, of the enum is in the range of the target type.</li>
|
|
<li>3: get value until it is not an any. Then convert it with the other rules.</li>
|
|
<li>4: only converts if the value of the character is between 0 - 255.</li>
|
|
<li>5: only converts if the value represents a decimal, hexadecimal (0x...) or a floating point number.
|
|
Examples: 10, 0x10, 10.045, 10,555, +10, +10.6e10, -10.6e-10, .16.</li>
|
|
<li>7: only converts if the value is in the range of the target type.
|
|
The value is rounded to an integer.</li>
|
|
<li>8: only converts if the float can be converted back to the same enum value.</li>
|
|
<li>9: only converts if the number is one of the enumeration type values. Normally you need
|
|
reflection information of the enum type.</li>
|
|
<li>10: only converts if it is the same enumeration type.</li>
|
|
<li>11: only converts if the string contains the name of an enumeration type value. Normally you need
|
|
core reflection information of the enum type.</li>
|
|
<li>12: only converts if the value of the string is "1", "true" or "0", "false". The comparision
|
|
is case insensitive.</li>
|
|
<li>13: only converts if the length of the string is 1 or 0.</li>
|
|
<li>14: only converts if the types are equal or the source type is derived from the destination
|
|
type.</li>
|
|
<li>15: only converts if each element of the source sequence can be converted to an element
|
|
of the destination sequence.</li>
|

</ul>
