Type name is invalid.
Error message
Type name is invalid.
What it means
Utility.Assembly.GetType looks up a type by name among registered assemblies, using a cache. The type name is required, and this exception is thrown when the supplied name is null or the empty string.
Solutions
- Validate the type name is non-empty before calling GetType
- Fix the configuration/data source that produced the blank name
- Check upstream string parsing (Split, Substring) that may yield an empty string
- Add a null/empty guard or default value at the config-loading boundary
Example fix
// before
string typeName = config.TypeName; // may be ""
Type t = Utility.Assembly.GetType(typeName);
// after
if (string.IsNullOrEmpty(config.TypeName)) throw new ArgumentException("TypeName missing in config");
Type t = Utility.Assembly.GetType(config.TypeName); Defensive patterns
Strategy: validation
Validate before calling
if (string.IsNullOrEmpty(typeName)) throw new ArgumentException("typeName is required", nameof(typeName)); Type guard
bool IsValidTypeName(string typeName) => !string.IsNullOrEmpty(typeName);
Try / catch
try { var t = Utility.Assembly.GetType(typeName); } catch (GameFrameworkException ex) { Log.Error($"Invalid type name '{typeName}'"); } Prevention
- Validate config fields for non-empty type names at load time
- Check string parsing/splitting that may yield empty results
- Provide defaults for optional type-name config entries
When it happens
Trigger: Calling Utility.Assembly.GetType(null) or GetType(""); passing a config-loaded type name that failed to deserialize into a non-empty string.
Common situations: Data-table/procedure type names read from config where the field is missing; string.Split or parsing producing an empty string; renamed type entries left blank in configuration.
