I was capturing some data from the CIM repository & the numbers I was receiving were just huge, so I wanted to make sure no data was lost when I brought the data into scope.
I had no clue what the max/min values of each type were, though, so I wrote the following code & thought it was worth sharing.
//Get all publicly available Type Codes (System.Int32, System.Char, etc.)
MemberInfo[] availableTypes = Type.GetType("System.TypeCode").GetFields();
Response.Write("<p style=\"font-family:Arial;font-size:9px\">");
//loop over each type & print all available fields
foreach(MemberInfo m in availableTypes){
try{
//Get all publicly accessible fields
FieldInfo[] allFields = Type.GetType("System." + m.Name).GetFields();
Response.Write("<br><br><b>" + m.Name + "</b>");
foreach(FieldInfo f in allFields){
Response.Write("<br> " + f.Name + ": "
+ Type.GetType("System." + m.Name).InvokeMember(f.Name,
System.Reflection.BindingFlags.GetField,
null,
null,
null).ToString());
}
} catch(Exception ex){
Response.Write("<br><br>" + m.Name + " blew up: " + ex.Message);
}
}
The preceding code produces the following results:
