Only primitive constants or arrays of primitives can be used as attribute parameters. The reason why is that an attribute must be encoded entirely in metadata. This is different than a method body which is coded in IL. Using MetaData only severely restricts the scope of values that can be used. In the current version of the CLR, metadata values are limited to primitives, null, types and arrays of primitives (may have missed a minor one). Decimals while a basic type are not a primitive type and hence cannot be represented in metadata which prevents it from being an attribute parameter." -- JaredPar, http://stackoverflow.com/questions/507528/use-decimal-values-as-attribute-params-in-c/507533#507533 The answer can be found in this Stack Overflow thread: http://stackoverflow.com/questions/507528/use-decimal-values-as-attribute-params-in-c
