靜態字典叫「System.TypeInitializationException」

Question

我有一個靜態類來保存字典和2種get方法來訪問它

這裏是我的類：

public static class ConfiguraCuadros 
    {  
    public static Dictionary<string,Dictionary<string,Dictionary<string,Dictionary<string,string>>>> GetDictionary() 
     { 
      // Try to get the result in the static Dictionary 
      return _configcuadros; 
     } 

     public static Dictionary<string, Dictionary<string, Dictionary<string, string>>> GetHoja(string key) 
     { 
      // Try to get the result in the static Dictionary 
      Dictionary<string, Dictionary<string, Dictionary<string, string>>> result = new Dictionary<string, Dictionary<string, Dictionary<string, string>>>(); 
      if (_configcuadros.TryGetValue(key, out result)) 
      { 
       return result; 
      } 
      else 
      { 
       return null; 
      } 
     } 

    public static readonly Dictionary<string, Dictionary<string, Dictionary<string, Dictionary<string, string>>>> _configcuadros = new Dictionary<string, Dictionary<string, Dictionary<string, Dictionary<string, string>>>> 
    { 

    { "Formato01", //this is just a hint, the dictionary is much more extensive 
       new Dictionary<string, Dictionary<string, Dictionary<string, string>>> 
       { 
        { 
         "F01C01A",  
         new Dictionary<string, Dictionary<string, string>> 
         { 
          { 
           "X", 
           new Dictionary<string, string> 
           { 
            { "key1" , "value1" }, 
            { "key2" , "value2" }, 
            { "key3" , "value3" }, 
           } 
          }, 
         } 
        }, 

       } 

      }, 
     } 
    }` 

當我使用getter方法，

ConfiguraCuadros.GetDictionary();

它拋出一個異常：

 
A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll 
'ConfiguraCuadros.GetDictionary()' threw an exception of type 'System.TypeInitializationException' 
    base: {"The type initializer for 'beDGRAIC.ConfiguraCuadros' threw an exception."} 
    TypeName: "beDGRAIC.ConfiguraCuadros" 

或

 
'ConfiguraCuadros.GetHoja("Formato01")' threw an exception of type 'System.TypeInitializationException' 
    base: {"The type initializer for 'beDGRAIC.ConfiguraCuadros' threw an exception."} 
    TypeName: "beDGRAIC.ConfiguraCuadros" 

正如你所看到的，我的意思是有一個靜態字典。我認爲問題出在字典聲明中......但我看不到在哪裏......

爲了以防萬一，「beDGRAIC」是我的名字空間。

感謝您的幫助！

你的代碼和我一樣工作（幾乎）。

我剛剛添加了一個缺少的分號讓它編譯，但可以在沒有任何異常的情況下調用ConfiguraCuadros.GetDictionary();。

下面是代碼後面與缺少分號：

public static class ConfiguraCuadros 
{ 
    public static Dictionary<string, Dictionary<string, Dictionary<string, Dictionary<string, string>>>> GetDictionary() 
    { 
     // Try to get the result in the static Dictionary 
     return _configcuadros; 
    } 

    public static Dictionary<string, Dictionary<string, Dictionary<string, string>>> GetHoja(string key) 
    { 
     // Try to get the result in the static Dictionary 
     Dictionary<string, Dictionary<string, Dictionary<string, string>>> result = new Dictionary<string, Dictionary<string, Dictionary<string, string>>>(); 
     if (_configcuadros.TryGetValue(key, out result)) 
     { 
      return result; 
     } 
     else 
     { 
      return null; 
     } 
    } 

    public static readonly Dictionary<string, Dictionary<string, Dictionary<string, Dictionary<string, string>>>> _configcuadros = new Dictionary<string, Dictionary<string, Dictionary<string, Dictionary<string, string>>>> 
     { 
      { "Formato01", //this is just a hint, the dictionary is much more extensive 
       new Dictionary<string, Dictionary<string, Dictionary<string, string>>> 
        { 
         { 
          "F01C01A",  
          new Dictionary<string, Dictionary<string, string>> 
          { 
           { 
            "X", 
            new Dictionary<string, string> 
            { 
             { "key1" , "value1" }, 
             { "key2" , "value2" }, 
             { "key3" , "value3" }, 
            } 
           }, 
          } 
         } 
        } 
       } 
     }; 
}

我不同意上司的評價上述有關檢查出的InnerException爲一個類型初始化異常的一般規則和特別是關於數據類型的不友好性質！
